seem (v.)

c. 1200, impersonal, hit semeth (it seems), "it appears (that something is so);" also with adjectives or phrases, "to appear to be (in some condition), have or present an appearance of being," from Old Norse soema "to honor; to put up with; to conform to (the world, etc.)," a verb derived from the adjective soemr "fitting."

This is reconstructed to be from Proto-Germanic *somiz (source also of Old English som "agreement, reconciliation," seman "to conciliate," source of Middle English semen "to settle a dispute," literally "to make one;" Old Danish söme "to be proper or seemly"), from PIE *somi-, suffixed form of root *sem- (1) "one; as one, together with" (also compare same).

Also in Middle English "to present oneself, appear; be visible, be apparent" (late 14c.), hence, of a fact, etc., "be evident, apparent, or obvious." The sense of "be fitting or appropriate, be expedient" (c. 1300) is the etymological one, but it is obsolete except in derived seemly, unseemly. Related: Seemed; seeming.
