Determinative Compounds.—In most determinative compounds the first part modifies or determines the second part: the modifier stands first, the principal word second.
Thus by hand-work a particular kind of work is meant, as contrasted with machine-work; cp.
a. The first part may be an adjective, an adverb, a preposition, an inseparable prefix, or, in a few cases, a substantive.
