an Abhidhamma term signifying a 'state of consciousness arisen spontaneously', i.e. without previous deliberation, preparation, or prompting by others; hence: 'unprepared, unprompted'.

This term and its counterpart (sasankhārikacitta, q.v.), probably go back to a similar distinction made in the Suttas (A.IV.171; "Path" 184).

See Tab. I; examples in Vis.M. XIV, 84f.
