Pronunciation

  • IPA: /ˈlæs.oʊ/, /læˈsuː/[1]

Etymology

It is borrowed from Spanish lazo (“snare, slipknot”),[2][3][4][5][6] from Latin laqueus (“noose, snare”).[3][4][5][6] The AHD traces it through Vulgar Latin *laceum.[2] It is related to lace.[2][4][6]

Earliest recorded meaning

A long rope of untanned hide with a noose at the end, used to catch cattle and wild horses (1768, as laço).[7][4]

Semantic evolution

The word is originally American English.[3][4] The modern spelling is recorded from 1808 for the noun;[4][5] the verb, to catch with a lasso, appears in 1807,[7][3][4][5] and was soon used figuratively.[7] Barnhart dates the noun only from 1819.[3] Etymonline notes that a lasso can serve as a lariat, but not the other way round.[4]
