locative singular of viññāṇa (consciousness); viññāṁ in standard texts
Analysis. vi + √ñā: vi (apart, in different directions) + ñā (knowing, perceiving) — knowing that is divided into distinct moments or appears in varied ways. Used in the phrase 'viññāṇasmiṁ' (in consciousness) to mark the location or domain where a mental process occurs, or as the pivot in dependent origination (paṭiccasamuppāda).
Etymology. From vi- (apart, asunder) + root √ñā (to know, perceive; cognate with Latin gnōscō 'to know', English 'know'). The prefix vi- gives the sense of discrimination or distinguishing awareness, hence consciousness as a faculty that discerns distinct objects. Compare Sanskrit vijñāna (cognition, consciousness).
