putative (adj.)

"supposed, reputed, commonly thought of or deemed," early 15c., from Late Latin putativus "supposed," from putat-, past-participle stem of Latin putare "to judge, suppose, believe, suspect," originally "to clean, trim, prune" (from PIE root *pau- (2) "to cut, strike, stamp"). At first especially in putative marriage, one which, though legally invalid due to an impediment, was contracted in good faith by at least one party. Related: Putatively.
