词源
from Latin retro 'backwards'.
retro-, prefix|ˈriːtrəʊ, ˈrɛtrəʊ|repr. the Latin adverb retrō backwards, back, which in the post-Augustan language appears in combination with various verbs and verbal nouns, as retroagĕre, -cēdĕre (-cessio, -cessus), -gradāre (-gradātio), -gradī (-gressus), -spicĕre, and more rarely in adjectival forms as retrōgradus. The use of the prefix was widely extended in mediæval Latin (see examples in Du Cange), but most of the important words in English which begin with it are derived from, or modelled on, the more classical types. The earliest to appear is the adj. retrograde, before 1400, followed in the 15th and 16th centuries by other forms from the same stem. Retrocedent and retroversion also appear in the 16th cent., but the main additions to the number are made in the 17th and following centuries. In the 19th, esp. the latter part of it, retro- has been very freely used as a prefix, chiefly in scientific terms (see examples under 3 below).2. The pronunciation of retro- is to some extent unsettled, and lexicographers vary in their recognition of, or preference for, the short or long vowel. Walker gives only the short, Smart only the long, while Webster admits both in all cases. Recent dictionaries which attempt to discriminate between the various words usually favour |ˈriːtrəʊ|, except in retrograde and retrospect.3. All the earlier or more important combs. of retro- are given below as main words; the following are illustrations of the extended use of the prefix in the 19th century. a. Miscellaneous terms, as retroaˈnalysis Chess, analysis of a position so as to reconstruct the moves of the game leading to that position; also transf.; so retroanaˈlytical a. retrocogˈnition, (a) knowledge of the past supernaturally acquired; (b) Psychol., paranormal cognition of events in someone or something else's past; so retroˈcognitive a. retroˈcoupling a., joining backwards or behind. ˈretrodate v., to put back to an earlier date. retrodisˈplacement, displacement rearwards. ˈretroflux, a backward flow. ˈretrofocus a. Photogr., designating an optical system in which the distance of the rear surface from the image of an object at infinity exceeds the focal length, usu. achieved by placing a diverging group of lenses before a converging group. ˈretroform v. (see quot.). retromiˈgration, migration back again. retro-ˈoperative a., having a retrospective effect. ˈretroplexed a., folded back upon itself. retropoˈsition, change of position in a backward direction. retroˈpresbyteral a., lying behind the presbytery (or choir and altar) of a cathedral or other large church. retroreˈception, the action of receiving back again. retroˈseer, one who sees into the past. retrosuˈsception, the action of taking back. retroˈtransfer, -ˈtransference, the act of transferring back again. retroˈvision, vision into or of the past.A number of similar forms are given in some Dicts., as retroclusion, -curved, -deflect vb., -deviation, -duct vb. -jection, -location, -morphosis, etc.[1933H.
