Flagged in 2-4% of sentences. A grammatically broken sentence doesn't just look unprofessional—it prevents your committee from evaluating your ideas.
Fix the broken grammar so the sentence conveys your intended meaning.
Sentence clarity issues go beyond simple typos or spelling errors. They're structural grammar problems that prevent the reader from understanding what you meant. Misplaced modifiers, subject-verb disagreement, dangling participles, and tangled syntax all fall into this category. Your committee can't evaluate an argument they can't parse.
These errors tend to emerge during revision, not during initial writing. You restructure a sentence, cut half of it, paste in a clause from another paragraph, and don't re-read the result. The sentence made sense in your head because you know what you meant to say. On the page, it's missing a verb, has a pronoun with no antecedent, or has a modifier attached to the wrong noun.
The most insidious clarity errors are the ones that are grammatically legal but semantically confusing. "The teacher who the student that the principal recommended evaluated the curriculum" is technically parsable, but no reader should have to diagram a sentence to understand your literature review. If a sentence requires more than one pass to understand, rewrite it—regardless of whether it's technically correct.
Committee members circle sentences with broken parallel structure or unclear grammar as confusing.
Students write convoluted sentences trying to sound scholarly. They add qualifiers, passive constructions, and embedded clauses, believing complexity signals intelligence.
Read your sentence aloud. If you stumble, your reader will too. The clearest sign of understanding is the ability to explain simply. Simplify first, then add necessary complexity back.
