Etymology
the word 'extract' originates from the latin verb 'extrahere', which is a compound of the prefix 'ex-' meaning 'out' and the verb 'trahere' meaning 'to pull or draw'. the past participle form 'extractus' gave rise to the english noun and verb. the core semantic logic has remained remarkably consistent: the act of pulling something out from a source, whether physically removing an object, obtaining a substance, or selecting a passage from a text. this journey from the literal latin action of drawing out to its various modern abstract and technical applications illustrates the durability of the underlying metaphor.
