nōnnumquam

Nonnunquam, sometimes in opp. to nunquam and semper, approximates to the meaning of sæpius, like ἔσθ’ ὅτε; interdum, at times, is in opp. to crebro, and approximates to the meaning of rarius, like ἐνίοτε; lastly, aliquando, now and then, is in opp. to semel, and approximates to the meaning of prope nunquam, like ποτέ. The interdum facta denotes actions repeated at considerable intervals of time; the nonnunquam facta, actions repeated at shorter intervals; the aliquando facta, actions repeated at very distant intervals of time.
