Morphology

attester = attest (transparent) = attest + er

Formed by the productive suffix '-er' on the verb 'attest' meaning 'one who attests', which is directly interpretable by learners.

Etymology

The word attester comes from the verb attest, from an old root that means 'witness' or 'give testimony', and it is the same root as testify and testimony. So an attester is literally someone who 'witnesses' or vouches that something is true.
