at SN.i.44 is metric spelling for sa-jīvana “same livelihood,” in phrase kiṃsu kamme s. “what is (of) the same livelihood in work, i.e. occupation?” The form is the same as jīvāna at Ja.iii.353. Taken wrongly as gen. pl. by Mrs. Rh. D. in translation (K.S. i.63): “who in their work is mate to sons of men?” following Bdhgh’s wrong interpretation (see K.S. i.321) as “kammena saha jīvantānan; kammadutiyakā nāma honti.”

sa² = saṃ, + jīvana
