Words related to hemi-


before vowels sem-, word-forming element meaning "half, part, partly; partial, imperfect; twice," from Latin semi- "half," from PIE *semi- "half" (source also of Sanskrit sami "half," Greek hēmi- "half," Old English sam-, Gothic sami- "half").

Old English cognate sam- was used in such compounds as samhal "poor health," literally "half-whole;" samsoden "half-cooked," figuratively "stupid" (compare half-baked); samcucu "half-dead," literally "half-alive;" and the last survivor of the group, sandblind "dim-sighted" (q.v.). Common in Latin (as in semi-gravis "half-drunk," semi-hora "half hour," semi-mortuus "half-dead," semi-nudus "half-naked," semi-vir "half-man, hermaphrodite"). The Latin-derived form in English has been active in forming native words since 15c.

sandblind (adj.)

also sand-blind, "half-blind, partially blind, dim-sighted," c. 1400, probably altered (by influence of unrelated sand (n.), perhaps as though "having grit in the eyes"), from Old English *samblind, with blind (adj.) + first element from West Germanic *sami-, from PIE *semi- (see semi-).

Now archaic or obsolete. Compare Old English samlæred "half-taught, badly instructed," samstorfen "half-dead," also later sam-hale "in poor health," literally "half-whole;" sam-sodden "half-cooked." Also compare purblind.
