"to draw out, withdraw, take or get out, pull out or remove from a fixed position, literally or figuratively," late 15c., from Latin extractus, past participle of extrahere "draw out," from ex "out, out of" (see ex-) + trahere "to draw" (see tract (n.1)). Related: Extracted; extracting.

early 15c., "process of withdrawing or obtaining" (something, from something else), from Old French estraction "extraction, origin" (12c.) or directly from Medieval Latin extractionem (nominative extractio), noun of action from past-participle stem of Latin extrahere "to draw out" (see extract (v.)). Meaning "that which is extracted" is from 1590s. Meaning "descent, lineage" is from late 15c.

This word might be adopted in our language with advantage, as we have none which conveys the same meaning. Extradition signifies the delivering up of criminals who may have sought refuge in any country, to the government whose subjects they are, on a claim being made to this effect. [from a footnote to the word extradition in the translation of "Memoirs of Marshal Ney" published in London in 1833]
