οβριμόθυμος
From LSJ
ἐὰν ταῖς γλώσσαις τῶν ἀνθρώπων λαλῶ καὶ τῶν ἀγγέλων, ἀγάπην δὲ μὴ ἔχω, γέγονα χαλκὸς ἠχῶν ἢ κύμβαλον ἀλαλάζον → though I speak with the tongues of men and of angels and have not charity I am become as sounding brass or a tinkling cymbal
Greek Monolingual
ὀβριμόθυμος, -ον (Α)
ορμητικός, τολμηρός, με ισχυρή ψυχή.
[ΕΤΥΜΟΛ. < ὄβριμος «ισχυρός, δυνατός» + θυμός (πρβλ. μακρόθυμος)].
