Word Frequency Analysis: How to Catch Crutch Words & Strengthen Your Prose
Learn how word frequency analysis reveals hidden 'crutch words', measures lexical diversity, and transforms repetitive first drafts into polished, authoritative prose.
Every writer has unconscious verbal ticks. When you are engrossed in the flow of drafting a chapter or an essay, your subconscious mind automatically falls back on familiar comfort words—commonly known as crutch words.
Word frequency analysis is an editorial method that counts and ranks every unique word in a document to expose overused filler words (such as "very", "really", "just", and "actually"). It measures lexical diversity (Type-Token Ratio), with 30% to 45% being the ideal benchmark for professional non-fiction and novel manuscripts.
Words like "very", "really", "just", "actually", and "perhaps" sneak into your paragraphs repeatedly. To the writer, they feel natural; to an editor or reader, they create a subtle feeling of monotony and dilute the authority of your claims.
The 10 Most Common "Crutch Words" and Stronger Alternatives
| Overused Crutch Word | Why It Weakens Writing | Stronger Replacement Strategy |
|---|---|---|
| Very / Really | Lazy intensifiers that add syllables without concrete imagery. | Use an exact, vivid adjective: "very cold" → freezing, "really angry" → furious. |
| Just | Diminishes confidence and makes claims sound apologetic. | Delete entirely: "I just think that..." → "The data indicates..." |
| That | Frequently used as an unnecessary restrictive conjunction. | In 60% of cases, deleting "that" tightens prose without changing meaning. |
| Suddenly | Tells the reader something was fast instead of creating tension. | Use a sudden short sentence or an active verb to evoke the surprise naturally. |
| Actually / Literally | Conversational filler that sounds defensive or informal in print. | State the factual observation directly without preparatory disclaimers. |
| Things / Stuff | Vague, abstract placeholders that demonstrate weak description. | Name the specific objects, variables, documents, or concepts. |
What is Lexical Diversity and What Score Should You Aim For?
Lexical diversity measures the vocabulary variety of a document using the Type-Token Ratio (TTR):
Lexical Diversity Formula
Lexical Diversity (%) = (Total Unique Words ÷ Total Words) × 100In short texts (under 500 words), lexical diversity naturally hovers around 50% to 65%. In long-form articles, essays, and novels (where recurring character names and topics accumulate), healthy lexical diversity sits between 30% and 45%.
If your article's lexical diversity falls below 25%, it is a clear warning that vocabulary repetition is excessive and needs synonym expansion.

What is a crutch word?
A crutch word is an unconscious verbal habit or repetitive filler word (such as "very", "really", "just", "actually", "basically") that writers lean on during first drafts, which weakens prose clarity.
What is a good lexical diversity score?
For long-form articles, essays, and novels, a healthy lexical diversity (Type-Token Ratio) is typically between 30% and 45%. Short texts under 500 words naturally score higher, around 50% to 65%.
Can word frequency analysis help with SEO rankings?
Yes. Search algorithms evaluate topical depth by identifying semantic co-occurrences and entity keywords. Checking word frequencies confirms that related core concepts are present across your article.
