Grammatical sense of "a member of a sentence expressing that on which the action of the verb is exerted" is from 1729.
No object "not a thing regarded as important" is from 1782, in which the sense of object is "obstacle, hindrance" (c. 1500). As an adjective, "presented to the senses," from late 14c. Object-lesson "instruction conveyed by examination of a material object" is from 1831.
word-forming element making abstract nouns from adjectives and meaning "condition or quality of being ______," from Middle English -ite, from Old French -ete (Modern French -ité) and directly from Latin -itatem (nominative -itas), suffix denoting state or condition, composed of -i- (from the stem or else a connective) + the common abstract suffix -tas (see -ty (2)).
Roughly, the word in -ity usually means the quality of being what the adjective describes, or concretely an instance of the quality, or collectively all the instances; & the word in -ism means the disposition, or collectively all those who feel it. [Fowler]
