From the plural of Old Latin *grātis, from Proto-Italic *gʷrātis, from Proto-Indo-European *gʷérHtis, from the root *gʷerH- (“to welcome, greet, praise”) + *-tis (deverbal abstract noun–forming suffix). Cognates include Oscan 𐌁𐌓𐌀𐌕𐌄𐌝𐌔 (brateís), Paelignian brat, brais, Vestinian brat, Old Church Slavonic жрьти (žrĭti, “to offer, sacrifice”) and Sanskrit गूर्ति (gūrtí, “approval, praise, welcoming; benediction”). Compare grātia (“favor, esteem, regard, liking, love, friendship, partiality”).
This noun originally appeared only in the nominative and accusative plural (the genitive, dative, and vocative plural are unattested and ablative plural only rarely) and was used with agō (“to put in motion, move, lead, drive, tend, conduct”) when rendering thanks to the gods; grātiās agō was generally used for thanks between humans.
Third-declension noun (i-stem), plural only.
