Entries linking to unremitted
prefix of negation, Old English un-, from Proto-Germanic *un- (source also of Old Saxon, Old Frisian, Old High German, German un-, Gothic un-, Dutch on-), from PIE *n- (source of Sanskrit a-, an- "not," Greek a-, an-, Old Irish an-, Latin in-), combining form of PIE root *ne- "not." Often euphemistic (such as untruth for "lie").
The most prolific of English prefixes, freely and widely used in Old English, where it forms more than 1,000 compounds. It underwent a mass extinction in early Middle English, but emerged with renewed vigor 16c. to form compounds with native and imported words. It disputes with Latin-derived cognate in- (1) the right to form the negation of certain words (indigestable/undigestable, etc.), and though both might be deployed in cooperation to indicate shades of meaning (unfamous/infamous), typically they are not.
It also makes words from phrases (such as uncalled-for, c. 1600; undreamed-of, 1630s; uncome-at-able, 1690s; unputdownable, 1947, of a book; un-in-one-breath-utterable, Ben Jonson; etc., but the habit is not restricted to un-; such as put-up-able-with, 1812). As a prefix in telegramese to replace not and save the cost of a word, it is attested by 1936.
late 14c., remitten, "to forgive, pardon," from Latin remittere "send back, slacken, let go back, abate," from re- "back" (see re-) + mittere "to send" (see mission). Secondary senses predominate in English.
From c. 1400 as "refer for consideration or performance from one person or group to another;" early 15c. as "send to prison or back to prison." The meaning "allow to remain unpaid, refrain from exacting" (penalty, punishment, etc.) is from mid-15c. Meaning "send money (to someone) in payment" is recorded from 1630s.
