masc nom sg of avijjānusaya (noun)
Analysis. a-vijjā-nu-saya: negation-knowing + along-lying-down = the tendency to ignorance lying dormant alongside the mind, one of the four or five anusaya (underlying tendencies) that propel rebirth in the cycle.
Etymology. From a- (not) + vijjā (knowing, from √vid cognate with Latin videre, English wit), compounded with anusaya (a tendency, from anu- along + √śī to lie, cognate with English sit). The prefix a- is plain negation (like Greek a(n)-); anu- preserves its concrete sense of trailing behind or lying alongside; together the compound names the dormant force of non-knowing that clings to the mind.
