nt instr sg of mona (noun)
Etymology. Root √mun- (to be silent, to think) is related to Sanskrit mun- and ultimately to Proto-Indo-European *men- (to think, mind), which also gives English "mind", "mental", Latin "mens" (mind), and Greek "menos" (spirit, vigor). The semantic shift from "silence" to "wisdom" reflects the contemplative ideal: the sage is silent because absorbed in thought. The form with -a suffix denotes the abstract quality or state.
