grandaevus

1. Vetus homo (ἔτος) denotes an old man, from the fiftieth year of his life, in opp. to juvenis, a young man, like γέρων; whereas senex (ἄναξ? or ἕνους ἔχων?), an old man from his sixtieth year, with the accessory notion of his being worthy of respect, like πρεσβύτης; lastly, grandævus and longævus denote a very aged man, who has already exceeded the usual duration of life, and who is, consequently, somewhere about eighty or upwards. 2. Senecta denotes old age indifferently, merely as a period of life; senectus, as a venerable and experienced age, that commands respect and indulgence; senium, the infirm and burdensome age, which is to be looked upon as a disease. (iv. 89.)
