If you've ever been rejected for a grant you thought was perfect for your organization, jargon might have been the silent killer. Not the lack of merit. Not the budget. Not even the narrative structure. Just the sheer, unnecessary complexity of your language.
Grant reviewers read dozens—sometimes hundreds—of proposals. They're tired. They're looking for clarity. And when they encounter sentences like "the implementation of synergistic methodologies to leverage stakeholder engagement across vertically integrated organizational vectors," they don't think "impressive." They think "next."
Plain language grant writing isn't about dumbing down your work. It's the opposite. It's about honoring your readers' cognitive load and making it effortless for them to understand why your organization deserves funding. At grants.club, we've analyzed thousands of successful grant proposals, and the pattern is unmistakable: clarity wins. Not by accident, but by design.
Key Takeaways
- Jargon creates cognitive friction that leads to rejection, even with expert reviewers
- Plain language doesn't mean simplistic—it means accessible and precise
- Target a Flesch-Kincaid Grade Level of 8-10 for maximum impact
- Use the "elevator pitch" test to identify unnecessary complexity
- Technical language has a place, but not in executive summaries or abstracts
Why Jargon-Heavy Proposals Lose (Even With Expert Reviewers)
Here's what most grant writers don't understand: being an expert in a field doesn't mean you want to decrypt jargon in your spare time. Reviewers are tired. They're evaluating dozens of applications. They're making decisions under time pressure. And every extra second spent decoding language is a second of cognitive fatigue.
Cognitive Load Theory, developed by psychologist John Sweller, shows us why this matters. When readers encounter unnecessarily complex language, their working memory capacity gets consumed by decoding rather than evaluating. Instead of thinking "this is a brilliant approach to urban food insecurity," they're thinking "what does 'multi-stakeholder capacity optimization' actually mean?"
The result? Proposal rejection. Not because your work isn't excellent. Not because your plan lacks merit. Simply because the reviewer's mental energy ran out before they could fully appreciate what you're trying to accomplish.
The Science Behind Clarity
Research from the Plain Language Association demonstrates that clear writing increases comprehension by 20-30% compared to jargon-heavy alternatives. More importantly for grant writers, it improves evaluation scores by an average of 15%. That's not marginal. That's the difference between funding and rejection.
When you use plain language, reviewers can allocate their cognitive resources to assessing the quality of your idea, the strength of your approach, and the feasibility of your timeline—not to translation work.
The False Confidence Problem
Grant writers often use jargon because it feels authoritative. It sounds like expertise. But here's the truth: expertise doesn't require jargon. A truly expert marine biologist can explain ocean acidification to a layperson in clear, compelling language. A leading public health researcher can discuss vaccination efficacy without hiding behind medical terminology.
When you rely on jargon, you're often signaling the opposite of expertise. You're signaling that you can't translate complex ideas into understandable language—a crucial skill in grant writing, where your reviewer might not be a specialist in your field.
"Our organization will operationalize comprehensive stakeholder engagement mechanisms through multi-vectored outreach initiatives designed to catalyze synergistic community mobilization within socioeconomically vulnerable demographics."
"We will reach low-income residents through a combination of door-to-door outreach, community meetings, and partnerships with local organizations they already trust."
What Are the Plain Language Principles That Strengthen Grant Applications?
Plain language isn't one technique—it's a set of principles that work together to make your writing clearer, more persuasive, and more memorable. At grants.club, we've distilled these into five core principles that consistently improve grant outcomes.
1. Use Short, Active Sentences
Every word should earn its place. Passive voice buries the subject and makes sentences harder to parse. Active voice clarifies who's doing what.
| Passive (Weak) | Active (Strong) |
|---|---|
| Grant funding was provided by the organization to community partners. | We provided grant funding to community partners. |
| Educational outcomes were improved through implementation of the program. | The program improved educational outcomes. |
| Stakeholders were engaged in collaborative problem-solving processes. | We engaged stakeholders in collaborative problem-solving. |
Aim for an average sentence length of 15-20 words. This isn't arbitrary. Readability research shows that when sentences exceed 20 words, comprehension drops measurably. Break long thoughts into multiple shorter sentences.
2. Choose Common Words Over Rare Ones
Replace obscure terminology with everyday language. This doesn't mean losing precision—it means being specific in a way your reader actually understands.
Instead of "ameliorate," use "improve"
Instead of "utilize," use "use"
Instead of "leverage," use "use" or "apply"
Instead of "precipitate social cohesion," use "bring people together"
3. Put the Most Important Information First
Your reader's attention is a scarce resource. Use the "inverted pyramid" structure: lead with your main idea, then add supporting details. This is especially critical in abstracts, executive summaries, and the first sentence of each paragraph.
"After conducting extensive research on food system resilience across nine counties in the Midwest, exploring both supply chain vulnerabilities and community access barriers, we discovered that emergency food networks require stronger coordination mechanisms to function optimally, which is why we propose establishing a regional coordination hub."
"We will create a regional coordination hub to strengthen emergency food networks across nine Midwest counties. This hub will address two critical gaps: supply chain vulnerabilities and community access barriers."
4. Use Concrete Language, Not Abstractions
Abstract language requires more cognitive processing. Concrete language creates mental images and is easier to remember.
| Abstract | Concrete |
|---|---|
| Optimization of resource allocation | Using our budget more efficiently |
| Enhancement of human capital development | Helping residents develop job skills |
| Systemic barriers to equitable outcomes | Rules and practices that prevent Black families from buying homes in certain neighborhoods |
5. Explain Technical Terms on First Use
If you must use a specialized term, define it immediately in parentheses or in the sentence itself. Don't assume the reviewer knows your field's shorthand.
"We will use cognitive behavioral therapy (CBT), a evidence-based counseling approach that helps people change unhelpful thinking patterns, to address anxiety in our client population."
How Do You Measure and Target Readability?
Plain language isn't subjective. You can actually measure it using readability formulas. These aren't perfect, but they're useful indicators of whether your writing is accessible.
Key Readability Metrics
Flesch-Kincaid Grade Level: This is the most widely used metric for grant writing. It estimates the U.S. school grade level needed to understand your text on a first reading. A score of 8-10 is ideal for most grant proposals. This means your writing should be accessible to someone with an 8th to 10th-grade education—not because your readers are less educated, but because we all comprehend faster and with less cognitive effort when text is written at this level.
Flesch Reading Ease Score: This ranges from 0-100. Higher scores indicate easier reading. For grant writing, target 60-70. Anything below 50 is significantly harder to read.
Gunning Fog Index: Similar to Grade Level, but weights longer words more heavily. Aim for 10-12.
Tools to Measure Readability
| Tool | Cost | Best For |
|---|---|---|
| Hemingway Editor (hemingwayapp.com) | Free online; $19.99 desktop | Real-time readability feedback while you write |
| Grammarly | Free; Premium $12/month | Comprehensive writing analysis including readability |
| ProWritingAid | Free limited; $12-20/month | Detailed readability reports and editing suggestions |
| Microsoft Word | Included | Built-in Flesch-Kincaid scoring |
Your Readability Target by Section
- Executive Summary: Grade Level 7-9 (highest priority—reviewers spend most time here)
- Aims/Goals: Grade Level 8-10
- Narrative/Methods: Grade Level 9-11 (can be slightly higher here)
- Results/Expected Outcomes: Grade Level 8-10
- Budget Narrative: Grade Level 8-10
Pro Tip
- Check your readability after your first draft, then revise to lower the grade level
- Extremely high readability scores (Grade 14+) are a red flag in grant writing
- Use readability tools as guides, not gospel—prioritize clarity over perfect scores
How Do You Translate Highly Technical Work for Non-Specialist Reviewers?
This is where many excellent researchers and technical professionals stumble. You understand your work deeply—often too deeply to remember what a novice doesn't know. The solution isn't to oversimplify. It's to build a bridge from general concepts to specialized details.
The Elevator Pitch Test
Start with what I call the "elevator pitch test." Can you explain your entire project in 2-3 sentences that a high school graduate could understand? If not, you're not ready for the grant narrative.
Example: "We develop algorithms that help doctors diagnose cancer faster." That's good. You're leading with the outcome (faster diagnosis) and the beneficiary (doctors and patients), not the methodology (deep learning neural networks).
The "Problem-Solution-Impact" Framework
When translating technical work, structure your explanations around this framework:
- The Problem: What is broken or incomplete? Use concrete language. Avoid technical framing.
- Your Solution: What will you do? Briefly describe the approach, but focus on what you'll do, not how.
- The Impact: What will change? Focus on real-world outcomes, not academic metrics.
Problem: "Coral reefs are dying from warming ocean temperatures, and we don't fully understand why some reefs survive while others collapse."
Solution: "We will study corals in warming waters off Australia and the Caribbean to identify which species and genetic traits promote survival."
Impact: "We'll identify coral species that can withstand future warming, informing marine conservation decisions for the next 50 years."
The Analogy Technique
Analogies translate unfamiliar concepts into familiar territory. Compare your technical work to something the reviewer already understands.
Complex: "We employ machine learning algorithms with transformer-based architecture to optimize natural language processing in clinical documentation."
With Analogy: "We use AI trained on thousands of medical records to automatically organize clinical notes—much like how your email program learns to recognize spam. This saves doctors hours every week."
The Role of Definition, Not Deletion
You don't need to remove technical language entirely. You need to define it. There's a difference:
"We will use special sensors to detect problems in the brain."
"We will use fMRI (functional magnetic resonance imaging), a brain-scanning technique that detects areas of activity by measuring blood flow changes, to identify which brain regions are affected by the disease."
The Peer Review Test
Before submitting your grant, have 2-3 colleagues outside your field read your technical sections. Wherever they pause or ask questions is where your explanation needs simplification. This is especially valuable at grants.club, where we can connect you with peer reviewers who have grant-writing experience.
When IS Technical Language Appropriate in Grants?
Let's be clear: plain language doesn't mean eliminating all specialized terminology. There are moments when technical language is not just appropriate—it's essential. Understanding when to use it is part of being an excellent grant writer.
Appropriate Use of Technical Language
- Methodology sections of discipline-specific grants where all reviewers will be subject-matter experts in your field
- Budget justifications for specialized equipment or software that requires technical specifications
- Literature review sections where you're demonstrating command of recent research
- Complex data analysis procedures when explaining statistical methods to quantitative researchers
Inappropriate Use of Technical Language
- Executive summaries (you're introducing, not demonstrating expertise)
- Aims or objectives sections (your reader needs to understand what you're trying to accomplish)
- Significance/impact statements (you're explaining why this matters to society, not just specialists)
- Abstracts (serves as an entry point, not a specialist presentation)
- Any section where the term is followed by jargon instead of a definition)
The "Specialist Reviewer Only" Principle
Before using technical language, ask: "Are all reviewers for this grant guaranteed to understand this term without explanation?" If the answer is no, simplify or define it. grants.club's funding database can help you research who typically reviews grants in your field—this will inform your language choices.
"We will develop a novel distributed consensus mechanism based on Byzantine Fault Tolerant protocols to improve blockchain scalability." (Technical, but appropriate for computer science reviewers)
"We will utilize blockchain distributed ledger technology to optimize interoperability across heterogeneous EHR systems." (Unnecessarily technical for a community health emphasis)
"We will implement a secure system that allows patient health records to be shared between health centers without compromising privacy." (Clear to public health reviewers)
What Editing Techniques Transform Proposals for Maximum Clarity?
Writing a clear first draft is hard. Editing for clarity is a learned skill. These techniques will become automatic with practice, but even experienced grant writers use them systematically.
1. The Reverse Outline Technique
After you write a section, read through it and extract one sentence summarizing the main idea of each paragraph. Do these sentences, arranged consecutively, tell a coherent story? If not, your logic isn't clear—and neither will your narrative be to reviewers.
2. The "So What?" Test
After each claim you make, ask "so what?" If you can't answer that in one sentence, your reader won't understand why it matters. This forces you to make connections explicit rather than expecting reviewers to infer them.
"We have partnered with six community organizations."
"We have partnered with six community organizations that collectively serve 5,000 residents annually. This ensures our program reaches the neighborhoods with the highest health disparities."
3. The Read-Aloud Test
Read your proposal aloud—to yourself or a colleague. You'll catch awkward phrasing, repetition, and unclear logic that your eyes skip over while reading silently. When a sentence makes you pause or stumble, it needs revision.
4. The Acronym Audit
Too many acronyms (even when defined) create cognitive overload. Audit your draft: which acronyms are truly necessary? Consider spelling out important terms instead of creating new acronyms.
Instead of: "We will partner with LEAs, CBOs, and PHDs to operationalize our EBP within the DDA."
Write: "We will partner with school districts, community organizations, and health departments to implement our evidence-based program within the state developmental disability agency."
5. The Nominalizations Hunt
Nominalizations are nouns created from verbs (e.g., "implementation" from "implement," "evaluation" from "evaluate"). They weaken writing and increase complexity. Convert them back to verbs.
| Nominalization (Weak) | Verb Form (Strong) |
|---|---|
| Implementation of the program | We will implement the program |
| Evaluation of outcomes | We will evaluate outcomes |
| Engagement of stakeholders | We will engage stakeholders |
| Optimization of resources | We will optimize resources |
6. The Specificity Check
Vague language often hides in abstractions. Replace every vague modifier with specific information.
| Vague | Specific |
|---|---|
| We will enhance student engagement. | We will increase class attendance from 75% to 92% by implementing daily text message reminders. |
| This intervention has demonstrated efficacy. | In a randomized trial of 400 students, the intervention improved math scores by 18 percentile points. |
| Our team has extensive experience. | Our team has 47 cumulative years implementing youth employment programs, including 12 grants totaling $3.2M. |

Plain Language Is Your Competitive Advantage
In a competitive funding landscape, clarity isn't a nice-to-have. It's a strategic advantage. Every funder receives proposals from qualified organizations. The difference between funding and rejection often comes down to which proposal the reviewer understands most easily and remembers most vividly.
Plain language grant writing accomplishes both. It makes your brilliant ideas impossible to misunderstand. It demonstrates respect for the reviewer's time. And it fundamentally shifts the conversation from "does this organization have the expertise?" to "this organization has expertise AND can explain why their work matters in terms I immediately grasp."
The organizations winning grants in 2026 aren't the ones using the most sophisticated vocabulary. They're the ones whose proposals are crystal clear, deeply strategic, and designed specifically for their reviewers. You now have the principles, the tools, and the techniques to join them.

Frequently Asked Questions
Q: Will using plain language make my proposal seem less sophisticated?
A: No. Plain language demonstrates command of your subject matter. Anyone can hide behind jargon. Only true experts can explain complex ideas clearly. grants.club reviewers consistently rate clear proposals as more professional than jargon-heavy ones.
Q: What if my funder specifically asks for technical language?
A: Follow their guidance. However, in our experience, fewer than 5% of funders actually require complex language. Most say "keep it accessible" or don't specify. When in doubt, start with clear language and add technical detail only where required.
Q: How much revision time should I budget for clarity editing?
A: Plan for 25-40% of your total writing time. For a proposal taking 40 hours to write, budget 10-16 hours for revision focused specifically on clarity. This includes readability checking, peer review, and multiple editing passes.
Q: Can I sacrifice detail for clarity?
A: Never. Plain language and comprehensive detail aren't in conflict. You're not choosing between clarity and depth. You're presenting depth in a clear, accessible way. Every detail you include should be explained in language your reader understands.
