κρῆσαι
From LSJ
περὶ οὐδὲν γὰρ οὕτως ὑπάρχει τῶν ἀνθρωπίνων ἔργων βεβαιότης ὡς περὶ τὰς ἐνεργείας τὰς κατ' ἀρετήν → since none of man's functions possess the quality of permanence so fully as the activities in conformity with virtue
Greek (Liddell-Scott)
κρῆσαι: ἀντὶ κεράσαι, ἀπαρέμφ. ἀορ. αʹ ἐνεργ. τοῦ κεράννυμι, Ὅμηρ.
