guarantor

Etymology

It is formed from English guarantee + -or,^[2][3][4] the agent suffix replacing the correlative ending -ee.^[2][3] The Shorter Oxford sees the model of warrantor,^[4] and Merriam-Webster Unabridged and Klein take the base as guaranty instead,^[5][6] which goes back to Anglo-Norman guarantie, also warantie, the source of warranty.^[3] The base noun is an alteration,^[2][7] perhaps by way of Spanish garante,^[2][3] or under the influence of words such as assignee and lessee,^[5] of Middle English garant (“warranty”),^[7] from Old French garant (“defender, protector; warranty; pledge”),^[2][5] which is also the source of warrant.^[3] The French noun is of Germanic origin,^[2][5] and Etymonline traces it to Proto-Germanic *war- (“to warn, guard, protect”), from Proto-Indo-European *wer- (“to cover”),^[2] while Merriam-Webster Unabridged compares Old High German werēnto (“guarantor”).^[5]

Earliest recorded meaning

A person who undertakes to see that another's obligation is met: 1811, according to Etymonline.^[2] The OED's first record is in J. Bouvier's Law Dictionary (1853), as one who gives a guaranty or security.^[3]

Semantic evolution

Before this word existed, the person giving security was the guarantee itself, from 1679,^[3] and for a few years from 1684 also the guaranty.^[3] Guarantee then moved on to the pledge itself, a development Etymonline places in the 18th century.^[2] By 1853 Bouvier's dictionary used guarantee for the person to whom a guaranty is given, the correlative of guarantor.^[3] Merriam-Webster Unabridged also records a general sense, one that guarantees anything, with Carl Spaatz's phrase "the guarantor of our security" for the Strategic Air Command.^[5]

Timeline

• 1811 – a person bound to see that another's obligation is performed.^[2] Merriam-Webster Unabridged dates the word to about 1828,^[5] and the OED's first record is from 1853.^[3]

Usage notes

In law, a guarantor differs from a surety: the surety's liability begins together with the principal debtor's, the guarantor's only when the debtor defaults.^[9] Collins and the OED's British pronunciation stress the last syllable;^[8][3] the OED's American pronunciations and Merriam-Webster Unabridged allow the stress on either the first or the last.^[3][5]
