Morphology

extractive = extract (transparent) = ex + tract + ive

In this NLP sense, 'extractive' straightforwardly means based on extracting material from the source text rather than generating new wording.

Etymology

Extractive comes from ex- 'out' and tract 'pull', just like tractor. In computer summaries, an extractive approach 'pulls out' exact sentences or words from the original text instead of creating new phrasing.
