valeō

Ave (from εὖ) is a salutation used at meeting and at parting, like χαῖρε; whereas salve is used at meeting only, vale at parting, like ἔῤῥωσο. Suet. Galb. 4. Ut liberti mane salvere, vespere valere sibi singuli dicerent. (i. 28.)

1. Posse and quire were originally transitive; posse (from πότνιος) denotes being able, as a consequence of power and strength, like δύνασθαι; quire (κοεῖν) as the consequence of complete qualification, like οἷόν τ’ εἶναι. Cic. Tusc. ii. 27. Barbari ferro decertare acerrime possunt, viriliter ægrotare non queunt; whereas valere and pollere are intransitive. Hence we say, possum or queo vincere, but valeo or polleo ad vincendum. 2. Valere (from ἑλεῖν) means to possess the right measure of strength, and thereby to match another, in opp. to insufficient strength, like σθένειν; whereas pollere (πολλός) means to have very considerable strength and means, and thereby to distinguish one’s self from others, in opp. to an ordinary degree of strength, like ἰσχύειν. iv. (160.)

1. Salus denotes existence in general, in opp. to interitus; whereas sanitas, the health of the person existing, in opp. to ægritudo; first of the body, then, in a higher degree, of the soul. 2. Sanus and valens denote health as a temporary state, and are allied in sense with integer; whereas saluber and validus denote habitual qualities, and are allied in sense with robustus. Hence salubris oratio means a speech sound in matter, possessing original strength; sana, a temperate and discreet speech. Cic. Brut. 13. 51. Tac. Dial. 25. Plin. Ep. ix. 26. 3. Sanus and saluber represent health, merely as finding one’s self well; valens and validus, as possessing strength to act. 4. Saluber in a transitive sense means, what brings sanitas, in opp. to pestilens, like ὑγιεινός; whereas salutaris, what brings salus, in opp. to pestiferus, like σωτήριος. Cato, apud Plin. H. N. xviii. 6. Nihil salutare est nisi quod toto anno salubre. (i. 31.)
