Morphology

certify = certain (transparent) = cert + ify

Clearly formed from 'certain' + '-ify' meaning 'make certain' or 'attest', matching the sense 'formally attest or provide evidence'.

Etymology

The word certify comes from the Latin parts certus ('sure') and facere ('to make'). So to certify something by proof or behaviour is to show or prove it and make it 'certain'.
