ἀλανέως
From LSJ
τοῖς πράγμασιν γὰρ οὐχὶ θυμοῦσθαι χρεών· μέλει γὰρ αὐτοῖς οὐδέν· ἀλλ' οὑντυγχάνων τὰ πράγματ' ὀρθῶς ἂν τιθῇ, πράξει καλῶς → It does no good to rage at circumstance; events will take their course with no regard for us. But he who makes the best of those events he lights upon will not fare ill.
Spanish
con seguridad, con toda garantía, totalmente, por completo
Greek (Liddell-Scott)
ἀλανέως: «ὁλοσχερῶς, Ταραντῖνοι», Ἡσύχ.
