The act or process of joining or adding something to another thing; the state of being joined or added.
From Latin 'adjectio' meaning an adding or joining, derived from 'adjicere' (to throw toward or add), composed of 'ad-' (to) and 'jacere' (to throw).
The word 'adjective' comes from the same Latin root—both describe something that gets 'thrown toward' a noun to modify it, which is exactly what adjectives do grammatically!
