Etymologically, the entry records: From Middle English demonstrable, from Old French.

For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is demonstrable, spelled D-E-M-O-N-S-T-R-A-B-L-E, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
