Analysis. a- (prefix, not) + pajānati (knows distinctly) = appajānati (does not know distinctly), with -anta forming the present participle. The prefix a- negates the factual knowing expressed by pajānati.
Etymology. The root is √jñā (know), with pa- (forward, forth) intensifying it into pajānati (knows distinctly, discriminates). The prefix a- is plain negation (cognate with English un-, Greek a(n)- in atheist). So appajānanta literally 'not knowing-forth', i.e. not discriminating or not clearly apprehending.
