Morphology

infrequent = frequent (transparent) = in + frequent

This is a standard negative-prefix formation meaning simply 'not frequent'.

Etymology

Infrequent starts with in- meaning 'not' and the rest, frequent, means 'happening often', as in frequency. So infrequent means 'not happening often'.
