etymonline
position (n.)
late 14c., posicioun, as a term in logic and philosophy, "statement of belief, the laying down of a proposition or thesis," from Old French posicion "position, supposition" (Modern French position) and directly from Latin positionem (nominative positio) "act or fact of placing, situation, position, affirmation," noun of state from past-participle stem of ponere "put, place." Watkins tentatively identifies this as from PIE *po-s(i)nere, from *apo- "off, away" (see apo-) + *sinere "to leave, let" (see site). But de Vaan identifies it as from Proto-Italic *posine-, from PIE *tkine- "to build, live," from root *tkei- "to settle, dwell, be home" (see home (n.)).
The meaning "place occupied by a person or thing" especially a proper or appropriate place, is from 1540s; hence "status, standing, social rank" (1832); "official station, employment" (1890). The meaning "manner in which some physical thing is arranged or posed, aggregate of the spatial relations of a body or figure to other such bodies or figures" is recorded by 1703; specifically in reference to dance steps, 1778, to sexual intercourse, 1883. Military sense of "place occupied or to be occupied" is by 1781.
position (v.)
1670s, "to assume a position" (intransitive), from position (n.). Transitive sense of "place or put in relation to other objects," now the usual meaning, is recorded from 1817. Related: Positioned; positioning.
