#GR11
Plural/singular error
A noun's number has to match what it's counting: one thing stays singular, more than one needs a plural form — and some nouns break the -s pattern entirely. Our mainframes flag a mismatch as #GR11, and in IELTS Writing Task 2 it counts against Grammatical Range & Accuracy every single time.
Each gap shows the noun's dictionary (singular) form in a chip. Type the form the sentence actually needs — sometimes that's a plural, sometimes it's the same singular form left unchanged.
Exam result
Step 1 Ask: is this one thing, or more than one?
Step 2 Check whether the noun is regular, irregular, uncountable, or invariant.
Step 3 Write the form the sentence needs, not the form you saw first.
In your next essay, do one dedicated pass that checks only noun number — and watch this error's count drop in your writing passport.
