fateor

Latin

From Proto-Italic *fatēōr, from Proto-Indo-European *bʰeh₂- (“to speak”); the stem fat- seemingly comes from Proto-Indo-European *bʰh₂-tó-s (“spoken”) (cognate with Ancient Greek φᾰτός (phătós)) or Proto-Indo-European *bʰh₂-t- (“who speaks”).^[1] Related to Latin for (“I speak, I say”), Latin fātum (“fate”), Latin fāma (“fame, reputation”), Ancient Greek φήμη (phḗmē, “talk”).
