Pronunciation

  • UK: /ˈwɒɹ.ən.ti/[1]
  • US: /ˈwoɹ.ən.ti/[1]

Etymology

It is inherited from Middle English warantie,[2][3][4] borrowed from Anglo-Norman warantie and Old Northern French warantie,[5][2][3][6][7] a dialect variant of Old French guarantie or garantie, modern French garantie.[5][7][8] It was formed from warant (“protector, guarantor”), the source of warrant,[5][2][3] with the suffix that gives English -y;[3][6] the American Heritage Dictionary and Merriam-Webster derive it from the feminine past participle of warantir (“to guarantee”).[9][10] The Old French noun is of Germanic origin,[9][5] from Frankish *warand, from a Proto-Germanic base meaning "to warn, guard, protect",[2] and Watkins places it under Proto-Indo-European *wer- (“to cover”).[2][9] In Anglo-Norman, where it is recorded from the late 12th century, the word already meant security or protection, a guarantee, and a clause in a deed binding the seller to warrant the title.[11] The same French word, in its central form, gave guaranty and guarantee, so warranty is a doublet of guaranty.[3][6][5]

Earliest recorded meaning

A covenant attached to a deed conveying land, by which the seller guarantees the title: 1338, in R. Mannyng's Chronicle,[5] or before 1338 according to Barnhart.[3] Etymonline describes it as a legal term for several kinds of clause in property transactions, from the mid-14th century.[2]

Semantic evolution

The word spread from property law to other contracts: from 1543 it meant an undertaking by one party that a statement is true or that goods are as described,[5] and after 1817 also an engagement by the insured, in an insurance contract, that certain facts are true or conditions will be met.[5] The general sense of a guarantee or assurance appears in 1555, in R. Eden's translation of Peter Martyr,[5][3] and the OED notes that it is now dialectal; in Scots and Northumberland speech the word meant both a legal warrant and a guarantee.[5][12] The sense "authority, sanction", recorded by Etymonline from the early 15th century[2] and by the OED from Spenser (1591), is now rare,[5] while "justifying reason, grounds" dates from 1836.[5] Johnson (1755) gave the common-law sense first, a promise in a deed securing another person in the enjoyment of something, and then "authority; justificatory mandate".[13] The usual modern sense, a maker's written guarantee to repair or replace a faulty product, is recorded in Merriam-Webster's Collegiate and the American Heritage Dictionary.[14][9]
