Pronunciation

Forms

allier[1] Old French alier, aleier and aloier; in the metal sense also allayer (1389) and aloyer (1547).[2][3]

Etymology

It is inherited from Old French alier, inherited from Latin alligō (“to bind to”), formed from ad- and ligō (“to bind”).[2][4][3][5][1] The TLFi calls the sense “to join” a borrowing from the Latin verb, which already meant “to unite” in Cicero.[6] The Old French variant aloier gave aloi, and Wiktionary calls the form aloyer a doublet.[3][1]

Cognate with Italian allegare (“to alloy”), Spanish allegar (“to gather”) and Spanish aliar.[3][5]

Earliest recorded meaning

It is first found in the Chanson de Roland (about 1100), as s'alier “to join, rally”: the knight bears the dragon a cui sa gent s'alient, round which his people rally.[6][5]

Semantic evolution

In Old French the verb meant “to gather, unite” of people, a sense now gone that lives on in rallier, and “to make an alliance” (1165–1170); soi allier “to join forces” (12th century) survived, while s'allier “to become friends” (1538) disappeared.[2] The sense “to become related by marriage” dates from the 16th century, in Amyot.[2]

The sense “to combine metals” is found in the Roman d'Alexandre (1170–1200) and of coinage in 1359; it gave aloi and alliage.[6][2][3] The verb also meant “to tie, bind” (about 1280, in Picard), from which, according to Wartburg, came the abstract sense “to join two different things” (Pascal, 1657).[2]
