unhonored (adj.)

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.

mid-13c., honuren, "to do honor to, show respect to," from Old French onorer, honorer "respect, esteem, revere; welcome; present" (someone with something), from Latin honorare "to honor," from honor "honor, dignity, office, reputation" (see honor (n.)). From c. 1300 as "confer honors on." From c. 1300 as "to respect, follow" (teachings, etc.). In the commercial sense of "accept a bill due, etc.," it is recorded from 1706, via the notion of "perform a duty of respect toward." Related: Honored; honoring.

A custom more honoured in the breach than the observance. Whoever will look up the passage (Hamlet I. iv. 16) will see that it means, beyond a doubt, a custom that one deserves more honour for breaking than for keeping: but it is often quoted in the wrong & very different sense of a dead letter or rule more often broken than kept.
