Century Dictionary and Cyclopedia

1. A termination of some English adjectives and nouns from adjectives, and of some verbs, derived from the Latin, as in apposite, composite, opposite, exquisite, requisite, erudite, recondite, etc. Its use in verbs, as in expedite, extradite, ignite, unite, and in nouns not directly from adjectives, as in granite, is less common. When the vowel is short, the termination is often merely -it, as in deposit, reposit, posit, merit, inhabit, prohibit, etc. It is not used or felt as an English formative. In a few words, as appetite, audit, from Latin nouns of the fourth declension, no adjective form intervenes.
2. A suffix of Greek origin, indicating origin or derivation from, or immediate relation with, the person or thing signified by the noun to which it is attached. Specifically— Noting a native or resident of a place: as, Stagyrite, a native of Stageira; Sybarite, a native of Sybaris, etc.
3. n. In chem., a suffix used not only in the names of salts derived from sulphurous acid, as calcium sulphite, but also in the names of certain substances belonging to the class of sugars, as mannite and dulcite, though these latter names are now systematically made to end in -ol (indicating chemical relation to the alcohols), as mannitol and dulcitol; also used without technical precision in names of pharmaceutical and commercial products, as glycerite, dynamite, vulcanite, etc.
