"art of moving, quartering, and supplying troops," 1846, from French (l'art) logistique "(art) of quartering troops," which apparently is from logis "lodging" (from Old French logeiz "shelter for an army, encampment," from loge; see lodge (n.)) + Greek-derived suffix -istique (see -istic). The form in French was influenced by logistique, from the Latin source of English logistic. Related: Logistical.
adjective ("pertaining to or indicating character") and noun ("a distinctive trait; that which gives or indicates character") both first attested 1660s, from character + -istic on model of Greek kharaktēristikos. Earlier in the adjectival sense was characteristical (1620s). Related: Characteristically (1640s). Characteristics "distinctive traits" also attested from 1660s.
