Cowgill's law, named after Indo-Europeanist Warren Cowgill, refers to two unrelated sound changes, one occurring in Proto-Greek and the other in Proto-Germanic. ==Cowgill's law in Greek== In Proto-Greek, Cowgill's law says that a former /o/ vowel becomes /u/ between a resonant (/r/, /l/, /m/, /n/) and a labial consonant (including labiovelars), in either order. Examples: *núks "night" < PIE '' *nokʷts'' (cf. Lat. ''nox'', Ved. ''nák'' < '' *nakts'', Goth. ''nahts'', Hitt. gen. sg. ''nekuz'' /nekʷts/) *phúllon "leaf" < PIE '' *bʰolyom'' (cf. Lat. ''folium'') *múlē "mill" < PIE '' *mol-eh₂-'' (cf. Lat. ''molīna'') *ónuks "nail" (stem ónukh-) < early PG '' *onokʷʰ-'' < PIE ''h₃nogʷʰ-'' (cf. OE ''nægl'' < PGerm '' *nag-laz'') Note that when a labiovelar adjoins an /o/ affected by Cowgill's law, the new /u/ will cause the labiovelar to lose its labial component (as in ''núks'' and ''ónuks/ónukh-'', where the usual Greek change '' *kʷ'' > ''p'' has not occurred). 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Cowgill's law」の詳細全文を読む スポンサード リンク
