Pronunciation

  • /ˈæ.lɔɪ/, /əˈlɔɪ/[1]

Etymology

It is borrowed from Middle French aloi (“mixture of metals; comparative purity of gold or silver”), also alloy,[2][3][4][5] from Old French aloier (“to combine”), earlier aleier,[2][6][7][8] from Latin alligō (“to bind to”),[9][6][10] formed from ad- and ligō (“to bind, tie”),[10][9][8] from Proto-Indo-European *leig- (“to tie, bind”).[9][10] It replaced the older allay, Middle English alai, also allai, alei in Anglo-French, from the earlier Old French alei,[11][5][10][4] and Barnhart dates the change to 1604.[11] The verb is apparently the older verb allay altered after the noun,[2] or aloyer, now rare in French.[3][4][2] The Latin verb also gave ally,[11][12][13] and its root gave ligament, ligature and, through Old French, lien.[8]

Earliest recorded meaning

The comparative purity of gold or silver, its fineness: 1593, in Eliot's Ortho-epia Gallica.[2][3] Under the older form alai the word is recorded before 1325,[11] and Etymonline dates it to the early 14th century, for a noble metal's relative freedom from base metal.[9]

Semantic evolution

The word began in coinage, where the standard of a coin depended on how much baser metal was mixed with its gold or silver.[2][14] Johnson (1755) defined it as "baser metal mixed in coinage", quoting Locke.[14] From 1615 it meant the less valuable metal itself;[2] from 1689 a metal made by mixing a precious metal with a lesser one, or later any two or more metals;[2] the Oxford Dictionary of English dates the sense "mixture of metals" to the mid 17th century,[15] and Etymonline dates its use without reference to value to 1827.[9] Figurative senses grew alongside: intrinsic quality or character from 1594, something mixed in that spoils or debases what is good from 1602, and simply a blend of things from 1707.[2] Old French aloi was popularly connected with à loi, "according to the law", as if the mixture were set by legal standard, according to Littré, Skeat and Weekley.[12][13] From 1851 alloy alone could mean the alloy typical of a particular use, now especially one based on aluminium.[2] Pronunciation shifted too: early dictionaries gave stress only on the second syllable, while recent British dictionaries give it mostly on the first.[2]

Usage notes

The OED notes that some mid-20th-century dictionaries stressed the noun on the first syllable in its literal senses and on the second in its figurative ones; in the most recent pronouncing dictionaries first-syllable stress is the usual or only pattern for the noun.[2] For the verb, American dictionaries give first-syllable stress only as a less frequent alternative, and British ones usually not at all.[2]
