英文词源
sudden
**sudden: **[13] The etymological notion underlying _sudden _is of something approaching stealthily or without warning, so that it takes one by surprise. It comes via Anglo-Norman _sudein _from late Latin subitānus, an alteration of Latin _subitāneus _‘sudden’. This was derived from _subitus _‘sudden’, an adjectival use of the past participle of _subīre _‘approach stealthily’. And _subīre _was a compound verb formed from the prefix sub-, used here in the sense ‘secretly’, and _īre _‘go’ (source of English ambition, exit, issue, etc).
=> ambition, exit, issue
sudden (adj.)
early 14c., sodaine, from Anglo-French sodein or directly from Old French sodain, subdain "immediate, sudden" (Modern French soudain), from Vulgar Latin *subitanus, variant of Latin subitaneus "sudden," from subitus past participle of subire "go under; occur secretly, come or go up stealthily," from sub "up to" (see sub-) + ire "come, go" (see ion). "The present spelling was not finally established till after 1700" [OED].
Noun meaning "that which us sudden, a sudden need or emergency" is from 1550s, obsolete except in phrase all of a sudden first attested 1680s, also of a sudayn (1590s), upon the soden (1550s). Sudden death, tie-breakers in sports, first recorded 1927; earlier in reference to coin tosses (1834). Related: Suddenness.
