Morphology

testify = test (semi-transparent) = test + ify

The surface segmentation 'test' + '-ify' is clear, but the formal legal meaning 'give testimony' relies on 'testimony/witness' sense rather than the everyday 'test' meaning.

Etymology

Testify comes from the Latin word testis 'witness', and it originally meant to 'give witness' in front of others. So to testify in a court is to formally tell what you saw or know as a witness.
