uh-TEST/əˈtest/

To attest is to show or prove that something is true, often attest to + noun: her results attest to months of practice. Confirm is everyday; testify is closer in law (a person speaks); demonstrate is a close academic cousin. Attestation is a rarer noun (a formal statement). In speech, show or prove is enough. Do not use attest for a vague hunch — it claims evidence.
