“thankful” in Latin

By circumlocution; e.g., to feel thankful to one for anything, gratiam (rarely gratias) habere alicui (χάριν ἔχειν or εἰδέναι τινί, when the thing for which one feels thankful is either not expressed, as Cic., De Orat., 1, 24, extr., or it follows in a clause of its own with quod, as Cic. in Catil., 1, 5, 11; or in a clause subjoined by a relative agreeing with the person, which is put in the dative; as, I feel most thankful to him for having, etc., ego illi maximam gratiam habeo, qui me ea poena multaverit, Cic., Tusc., 1, 42, 100). To be thankful from the bottom of the heart, gratiam habere, quantam maximam animus capere potest: to feel thankful to anybody for having done anything, is gratiam habere alicui, qui... fecerit, etc.; but sometimes the indicative is used, to add more weight to the cause as a fact of actual occurrence: habeo senectuti magnam gratiam, quae mihi sermonis aviditatem auxit = for she has increased, etc., (Vid: Pr. Intr., App., 17).
