Forms

grātus (feminine grāta, neuter grātum, comparative grātior, superlative grātissimus, adverb grātē); first/second-declension adjective[1]

Etymology

It is inherited from Proto-Italic *gʷrāto- (“grateful”), inherited from Proto-Indo-European *gʷr̥H-tó- (“praised (in song)”), from the root *gʷerH- (“to welcome, praise”).[2][1]

Cognate with Oscan brateis (“of grace, favour”),[2] and with Sanskrit गृणाति (gṛṇā́ti, “praises, welcomes”).[2][1][3]

Earliest recorded meaning

It is found from Plautus onwards,[2][4] whose character says “I ought to have a grateful heart towards him”.[3]

Semantic evolution

It meant grateful or thankful, as Terence's “you will call me mindful and grateful” and Cicero's remark that grateful men are rare.[3] Of kindnesses it meant welcome and deserving thanks, and of things and people welcome, acceptable or popular, as a law grata populo, “welcome to the people”.[3] It also meant pleasant or charming, as Horace's “pleasing song”.[3]

Medieval Latin also used it for joyful,[5] and a noun gratum meaning favour or consent appears in the 10th century.[6][4] It survives as French gré and as Italian, Spanish and Portuguese grado and grato.[1] English grace comes from its derivative gratia, and grateful was formed in the 1550s from an obsolete adjective grate.[7]
