Etymology

It is inherited from Middle English prevailen, also prevalen,[2][3] borrowed from Middle French prévaloir (“to have the advantage, dominate”) and directly borrowed from Latin praevaleō (“to have superior force, have the upper hand”).[4][2][5][3] The Latin verb is formed from prae- (“before”) and valeō (“to be strong, have power”),[6][3][5] from Proto-Indo-European *wal- (“to be strong”).[3][6] The spelling with “-ai-” is probably due to avail and vail,[2][5][4] and Klein and Skeat take it from the Old French stem prevail.[7][8] In Anglo-Norman prevaler, to prevail or have greater authority, is recorded from 1489.[9] It is related to prevalent, valiant and value.[7][10]

Earliest recorded meaning

To become very strong, to gain force or vigour: before 1398, in Trevisa's translation of Bartholomew de Glanville; this sense was obsolete by 1755.[4][11] Barnhart and Etymonline date the sense "to be successful or effective" to before 1400, in a translation of Lanfranc's Science of Surgery.[5][3][4]

Semantic evolution

From the start of the 15th century prevail meant to be successful or effective, and to gain the mastery over an opponent (before 1425).[4][2] To prevail on or upon someone, to persuade them, is recorded from about 1450 in the OED,[4] though Etymonline dates it only to the 1570s.[3] In the 15th to 17th centuries the verb could also mean "to be of use to, benefit", like avail.[4] The modern sense of being the most frequent or most widespread, and then of being generally current, appears in the early 17th century: the OED cites 1612 and 1617,[4] Barnhart Hobbes's translation of Thucydides (1628),[5] and Etymonline gives "be in force, be current" only from 1776.[3] Johnson (1755) listed "to be in force, to have effect" first, and "to overcome, gain the superiority" second.[12]
