I'm writing a philosophy essay that pertains to subjectivity (the condition of being a subject of experience).
- I use subject in sentences like x is a subject if, and only if, x satisfies criteria x, y, z.
- I use term in sentences like The term denotes x.
- I use argument in sentences like John's argument for that claim procceeds thus:...
Is there a word that denotes 'the subject of a sentence' or 'the thing that satisfies predicates' that isn't term, subject, or argument?
I sometimes use work-arounds, such as the subject of a sentence and (grammatical) subject or (grammatical) argument. Nevertheless, there are cases where my sentences would read more easily if I could replace those work-arounds with a single word.
