## AI Etymology
Interstitial comes from Latin inter- ("between") + sistere ("to stand"), giving intersistere ("to stand between") and interstitium ("interval, space between"); via Late Latin interstitialis ("pertaining to an interval") into Modern English interstitial. In current use it is an adjective meaning "relating to or situated in the small spaces between things or parts". That sense is explained by the older material without requiring a speculative semantic step: the inherited or borrowed base supplies the field of meaning, while the English formation fixes its modern role. The surface form is compositional: its joined elements remain visible in the modern word. The word's history is thus visible in its construction: the components remain interpretable even after the whole expression has settled into a conventional English meaning.
