单词 relay
释义

relayn.1

Brit. /ˈriːleɪ/, U.S. /ˈriˌleɪ/
Forms: late Middle English rolay (transmission error), late Middle English 1600s– relay, late Middle English–1500s relaies (plural); also Scottish pre-1700 rela, pre-1700 relae.
Origin: A borrowing from French. Etymon: French relais.
Etymology: < Middle French, French relais hounds or (in later use also) horses held in reserve in a hunt (13th cent. in Old French), horses held in reserve for changing on a journey (1573), group of people who relieve others or operate in sequence (1616), place where horses are held in reserve, coaching inn, staging post (1671), resting place or guest house for long-distance travellers (1936 or earlier), either < relayer relay v.1 (probably influenced in form by relais release n.), or a spec. use of relais release n. after relayer relay v.1 N.E.D. (1906) gives the pronunciation (rĭlēi·) /rɪˈleɪ/. Pronunciation with stress on the first syllable is recorded as an alternative in Webster's New Internat. Dict. Eng. Lang. (1920) and alone in Webster's 3rd New Internat. Dict. Eng. Lang. (1961). It is given as an alternative by British dictionaries from the mid 20th cent. onwards and soon after that as the main or only pronunciation.
1. Hunting. A set of fresh hounds or (occasionally) horses posted to replace a tired set in a chase; spec. such a set of hounds released after a previous set has passed. Cf. vauntlay n. Now rare (chiefly archaic in later use).In early use also: †a place where such a set is posted (obsolete).

relayv.1

Brit. /rɪˈleɪ/, /ˈriːleɪ/, U.S. /riˈleɪ/, /rəˈleɪ/, /ˈriˌleɪ/
Forms: late Middle English rebaie (transmission error), late Middle English relaied (past participle), late Middle English relaye, late Middle English– relay.
Origin: Of multiple origins. Partly a borrowing from French. Partly formed within English, by conversion. Etymons: French relayer ; relay n.1
Etymology: Partly < Middle French, French relayer to change hounds during a hunt (13th cent.), to replace or relieve another person at work (1636) < re- re- prefix + Middle French regional (north-eastern) laier (12th cent. in Old French), of uncertain and disputed origin (perhaps originally either a variant of laisser (see lease v.3) or < an unattested Germanic cognate of leave v.1), and partly (especially in later use) < relay n.1 N.E.D. (1906) gives only the pronunciation (rĭlēi·) /rɪˈleɪ/. Pronunciation with stress on the first syllable is recognized in dictionaries slightly later in the verb than in the noun; it is not given in Webster's New Internat. Dict. Eng. Lang. (1920), for example, but is given as the BBC's recommended pronunciation for both noun and verb in the ‘broadcasting sense’ in D. Jones Eng. Pronouncing Dict. (ed. 4, 1937): compare etymology note at relay n.1
