Un-

Definition of Un-

	1.	An inseparable verbal prefix or particle. It is prefixed: (a) To verbs to express the contrary, and not the simple negative, of the action of the verb to which it is prefixed; as in un bend, un coil, undo, un fold. (b) To nouns to form verbs expressing privation of the thing, quality, or state expressed by the noun, or separation from it; as in un child, un sex. Sometimes particles and participial adjectives formed with this prefix coincide in form with compounds of the negative prefix un- (see 2d Un-); as in un done (from undo), meaning unfastened, ruined; and un done (from 2d un- and done) meaning not done, not finished. Un- is sometimes used with an intensive force merely; as in un loose.
adv.	1.	An inseparable prefix, or particle, signifying not; in-; non-. In- is prefixed mostly to words of Latin origin, or else to words formed by Latin suffixes; un- is of much wider application, and is attached at will to almost any adjective, or participle used adjectively, or adverb, from which it may be desired to form a corresponding negative adjective or adverb, and is also, but less freely, prefixed to nouns. Un- sometimes has merely an intensive force; as in un merciless, un remorseless.
	2.	Un- is prefixed to adjectives, or to words used adjectively.
	3.	To adjectives, to denote the absence of the quality designated by the adjective
	4.	To past particles, or to adjectives formed after the analogy of past particles, to indicate the absence of the condition or state expressed by them
