Parts of Speech
Nouns
A noun is the name of a person, place, thing, or idea — the anchor every sentence builds around.
Why this happens
Noun errors usually come from treating uncountable words as countable, mixing up singular and plural forms, or using a generic noun where a specific one is needed. In exam writing, vague nouns like thing or stuff weaken arguments, while wrong plurals (informations, advices) stand out immediately to markers. Spotting the noun first helps you choose the right article, verb, and modifier around it.

Teaching note: Data is traditionally plural; datas is non-standard in formal writing.

Subject names ending in -ics are usually singular (mathematics is) even though scores takes a plural verb.

Species is the same in singular and plural — let the determiner (one vs several) guide agreement.
