Morphology

exponent = ex + ponent + ent

Although formed from recognisable bound elements (ex- + -ent), the root 'ponent' is not a standalone English word and the mathematical sense is specialized, so learners cannot derive the meaning from the parts alone.

Etymology

Exponent comes from Latin parts ex- 'out' and ponere 'to put', the same root you can see in position. Think of an exponent as the small number 'put out' above and to the right of a base that tells how many times to multiply.
