“grateful” in Latin

gratus (in both senses of the English word, with dative in the sense of “agreeable;” with erga, adversus, in the sense of “thankful;” where it seems to take the dative in this sense, the dative belongs rather to the verb: it is not certain whether in aliquem or in aliquo is right, since in me, te does not decide this [Krebs]; it is safer to use the accusative): beneficiorum memor. (The words are found in this connection and order.) memor gratusque. To be grateful, gratum or memorem et gratum esse: to feel grateful, gratiam habere: to show one’s self grateful, alicui gratum se praebere; memorem in aliquem animum praestare: very grateful, gratissimo animo prosequi nomen alicujus; for anything, alicui pro re gratiam referre: both to be and to show one’s self grateful, re ipsa atque animo esse gratissimum; gratiam et referre et habere (referre, of an actual return; after Cic., Off., 2, 20, 69): not only to be grateful, but to have abundantly proved his gratitude, non habere modo gratiam, verum etiam cumulatissime retulisse (Cic.): to show one’s self exceedingly grateful, cumulatissimam alicui gratiam referre: to appear grateful, memorem gratumque cognosci: to endeavor to appear grateful, gratum me videri studeo: to retain a grateful recollection of anything, grate meminisse aliquid; grata memoria prosequi aliquid.
