savoir

French

Alternative forms

• sçavoir (obsolete)

Etymology

From Old French savoir, saveir, from Vulgar Latin *sapēre, from Latin sapĕre (“to taste”) (and "to know" in Late Latin, by influence of the adjective sapiēns (“wise”)), present active infinitive of sapiō. Ultimately from Proto-Indo-European *seh₁p- (“to try, to research”). The verb was for a long time spelled sçavoir from (deprecated template usage) [etyl] Middle French until the 18th century, by false regression to Classical Latin scīre "to know".

The forms of the verb with -ch- are a regular reflex of Latin -pi- (/-pj-/). Compare seiche, approcher, hache.
