Morphology

reciprocal = reciprocate + reciprocity (opaque) = reciproc + al

Formally the adjective is the combining stem plus -al (similar to the non-mathematical sense), but the stem is not a standalone English morpheme.

Etymology

Reciprocal comes from the Latin reciprocus, meaning 'returning', and in math it keeps the idea of 'giving back' — a reciprocal number is the one that 'returns' you to one when you multiply them. So the reciprocal of a number is the number you multiply by to get 1.
