viyatta : [adj.] learned; accomplished.

Viyatta (adj.) [cp. Sk. vyakta, vi+pp. of añj] determined, of settled opinion, learned, accomplished; only in stock phrase sāvakā viyattā vinītā visāradā (which Rh. D. trsls "true hearers, wise and well -- trained, ready etc." Dial. ii. 114) at D ii.104=A iv.310=S v.260=Ud 63. The BSk. (at Divy 202) has śrāvakāh (for bhikkhū!) paṇḍitā bhaviṣyanti vyaktā vinītā viśāradāh. <-> 2. separated, split, dissenting, heretic Sn 800 (=vavatthita bhinna dvejjhāpanna etc. Nd2 108; =bhinna SnA 530). Cp. the two meanings of vavatthita (=*vyakta), which quasi -- correspond to viyatta 1 & 2 At this passage the v. l. (all SS of the Commentary) viyutta is perhaps to be perferred to viyatta.
  Note. It is to be noted that viyatta in § 1 does not occur in poetry, but seems to have spelling viy˚ because of the foll. vinīta and visārada. Cp. vyatta & veyyatta.
