Pronunciation

Forms

fonder[1] Old French funder.[2][3]

Etymology

It is borrowed from Latin fundō (“to lay the foundation of, to establish”), early in the 12th century, from fundus (“bottom”).[4][2][5][6] Bloch and Wartburg note that it stayed in contact with written Latin, while Wiktionary treats it as inherited.[7][1]

Cognate with Italian fondare, Old Occitan fondar and Spanish fundar.[7][3][8]

Earliest recorded meaning

The verb is first found in the Cambridge Psalter (early 12th century), meaning “to set on foundations”: Ki fundad la terre sur sa basse (“who founded the earth on its base”).[2]

Semantic evolution

From the start it meant “to set on foundations”, whence the biblical images fonder sur le roc and fonder sur le sable.[4] As in Latin, it soon meant “to establish” a town, a religion or an enterprise (about 1160) and, in the abstract, “to base (something) on” (about 1190).[2][4] The past participle fondé meant “versed in” from about 1165;[2] from it came fondé en pouvoir (1601) and fondé de pouvoir (1792).[2][4] The sense “to give a reasonable basis to, to justify” dates from 1478–80, chiefly in bien fondé, and the legal sense “to provide the funds to set up” from 1690.[2][4]

Related nouns were taken from Latin: fondateur, with the older Old French fondeor, and fondation (13th century).[4] Refonder (1993) belongs to political vocabulary.[4] English found was borrowed from Old French fonder in the late 13th century.[9]
