sedge: [OE] The sedge is etymologically the plant with ‘cutting’ leaves. The word goes back to a prehistoric Germanic *sagjaz, which was descended from the Indo-European base *sek- ‘cut’ (source also of English saw, section, segment, sickle, etc). => section, segment
sedge (n.)
"coarse grass-like plant growing in wet places," Old English secg "sedge, reed, rush," from Proto-Germanic *sagjoz (cognates: Low German segge, German Segge), probably from PIE root *sek- "to cut" (see section (n.) and compare Old English secg, identical in form but meaning "sword;" and German schwertel-gras "sedge" from schwert "sword"), on notion of plant with "cutting" leaves (compare etymological sense of gladiolus). Old Irish seisg, Welsh hesgreed "rush" might represent a similar sense development from the same root. Often spelled seg, segg until present form triumphed early 1900s.
