addle (v.)[addle 词源字典]: 1712, from addle (n.) "urine, liquid filth," from Old English adela "mud, mire, liquid manure" (cognate with Old Swedish adel "urine," Middle Low German adel, Dutch aal "puddle").

Used in noun phrase addle egg (mid-13c.) "egg that does not hatch, rotten egg," literally "urine egg," a loan-translation of Latin ovum urinum, which is itself an erroneous loan-translation of Greek ourion oon "putrid egg," literally "wind egg," from ourios "of the wind" (confused by Roman writers with ourios "of urine," from ouron "urine"). Because of this usage, from c. 1600 the noun in English was taken as an adjective meaning "putrid," and thence given a figurative extension to "empty, vain, idle," also "confused, muddled, unsound" (1706). The verb followed a like course. Related: Addled; addling.[addle etymology, addle origin, 英语词源]
muddle (v.): 1590s, "destroy the clarity of" (a transferred sense); literal sense ("to bathe in mud") is from c. 1600; perhaps frequentative formation from mud, or from Dutch moddelen "to make (water) muddy," from the same Proto-Germanic source. Sense of "to make muddy" is from 1670s; that of "make confused" first recorded 1680s. Meaning "to bungle" is from 1885. Related: Muddled; muddling.
pre-: word-forming element meaning "before," from Old French pre- and Medieval Latin pre-, both from Latin prae (adverb and preposition) "before in time or place," from PIE *peri- (cognates: Oscan prai, Umbrian pre, Sanskrit pare "thereupon," Greek parai "at," Gaulish are- "at, before," Lithuanian pre "at," Old Church Slavonic pri "at," Gothic faura, Old English fore "before"), extended form of root *per- (1) "beyond" (see per).

The Latin word was active in forming verbs. Also see prae-. Sometimes in Middle English muddled with words in pro- or per-.
screw (v.): "to twist (something) like a screw," 1590s, from screw (n.). From 1610s as "to attach with a screw." Slang meaning "to copulate" dates from at least 1725, originally usually of the action of the male, on the notion of driving a screw into something. Meaning "defraud, cheat" is from 1900. First recorded 1949 in exclamations as a euphemism. Related: Screwed; screwing. To screw up "blunder" is recorded from 1942. Screwed up originally was figurative for "tuned to a high or precise pitch" (1907), an image from the pegs of stringed instruments. Meaning "confused, muddled" attested from 1943. Expression to have (one's) head screwed on the right (or wrong) way is from 1821.
woozy (adj.): "muddled or dazed, as with drink," 1897, American English colloquial, variant of oozy "muddy," or an alteration of boozy. It is recorded in 1896 as student slang, but with a sense "foolish, behind the times," also "pleasant, delightful."
