单词 atro-
释义

atro-comb. form

Stress is usually determined by a subsequent element and vowels may be reduced accordingly. Some degree of stress is usually maintained on the first syllable. If the subsequent element is an existing word, it is likely to retain its original stress pattern, e.g. atrosanguineous Brit. /ˌatrə(ʊ)saŋˈɡwɪnɪəs/, U.S. /ˌætroʊˌsæŋˈɡwɪniəs/.
Origin: A borrowing from Latin. Etymon: Latin atro-.
Etymology: < post-classical Latin atro-, combining form of classical Latin āter black < the same Italic base as Umbrian atru (neuter plural) black, perhaps < the same Indo-European base as Avestan ātarš fire, Early Irish áith drying-kiln (for grain), Welsh odyn kiln (perhaps with suffix), Armenian ayrem to burn, the sense hence being ‘blackened by fire’; compare -o- connective.Compare also Ukrainian vatra hearth, stove bottom, (regional) fireplace, fire, soot, hot coals, heat, Polish regional watra fire, soot, Serbian and Croatian vatra fire, Albanian vatër fireplace, hearth, either cognate with the forms above, or showing borrowing from another Indo-European language. Notes on specific formations. With atrorubent compare post-classical Latin atrorubens (1566 or earlier). With atrosanguineous compare scientific Latin atrosanguineus (1781 or earlier).
Combining form of Latin āter black, as in atrorubent reddish-black, atrosanguineous of a dark blood-red colour.
