Morphology

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

The noun shares the same morphological formation as the adjective (combining stem + -al) though the stem itself is not a standalone English word.

Etymology

Reciprocal comes from the Latin reciprocus 'returning' and shares the root with reciprocate; in math it means 'the thing that returns you to one', for example the reciprocal of 5 is one-fifth. So a reciprocal is the number that, when multiplied by the original, gives 1.
