position: [15] Position comes via Old French from Latin positiō, a noun formed from posit-, the past participial stem of Latin pōnere ‘put, place’. This was also the source of English posit [17], positive [13] (which etymologically means ‘placed down, laid down’, hence ‘emphatically asserted’), post (in the senses ‘mail’ and ‘job’), and posture [17].

And in addition it lies behind a wealth of English verbs (compose, depose, dispose [14], expose [15], impose, interpose [16], oppose, repose, suppose, transpose [14], etc) whose form underwent alteration by association with late Latin pausāre ‘stop’ (see POSE); postpone exceptionally has retained its link with pōnere.
