Morphology

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

Formally decomposes as 'test' + '-ify', but the modern meaning ('bear witness, provide evidence') aligns with 'testimony/witness' rather than 'make a test', so the relation is not fully obvious to learners.

Etymology

Testify comes from the Latin word testis, which means 'witness', and it is the same root as testimony; imagine a monument or clear fact that 'stands as a witness'. So when something testifies to something, it acts like evidence that shows the truth.
