subject
word
Definition
A subject is the topic being talked about, studied, or discussed. It can also mean a school class, the main noun or pronoun in a sentence, or a person/thing being studied in research.
Usage & Nuances
Very common and multi-meaning. The most frequent uses are 'topic' and 'school subject'. In grammar, 'the subject of the sentence' is a technical meaning. In research, 'test subject' is common. Be careful: as an adjective/verb, 'subject to' means 'affected by' or 'dependent on', but that is a different use.
