Pronunciation

Etymology

It is borrowed from Middle French pact, later pacte,[2][3] and directly borrowed from Latin pactum (“agreement, covenant”),[2][4][5] a noun use of the neuter past participle of paciscor (“to make a covenant, agree”).[4][5][6][3] The Latin verb is related to pāx (“peace”), the source of peace,[7][3][8] and to pangō (“to fix, fasten”).[5][9][10] They go back to Proto-Indo-European *pag- (“to fasten”),[4] and Barnhart and Merriam-Webster list as cognates Ancient Greek πήγνυμι (pḗgnūmi, “to fix, fasten”), Sanskrit पाश (pāśa, “noose, cord”) and Gothic 𐍆𐌰𐌷𐌰𐌽 (fāhan, “to catch”);[5][11] Merriam-Webster adds Old English fōn (“to take, seize”).[11] The French word is recorded from 1352–6.[2]

Earliest recorded meaning

A formal agreement between persons or parties: 1429, in the Rolls of Parliament.[2][5] Etymonline dates it to the early 15th century and Dictionary.com to 1400–50.[4][12]

Semantic evolution

The word has kept its meaning since the 15th century,[2][13] and Johnson (1755) defined it as a contract or covenant.[14] Merriam-Webster notes the special use for an international treaty.[11] A verb, to agree to something or to enter into a pact with someone, is recorded from 1535, in Thomas Cromwell, and the intransitive use from 1904.[2] Etymonline notes the related paction, the making of a pact.[4]
