show or prove something is true
To show clearly that something is true or real.
用法パターン：
[something] attests to [something]
よくある間違い：
Learners sometimes use 'attest' for everyday ideas like 'I can attest your English is good.' In casual speech, 'show' or 'prove' is more natural. Also, in this sense, the subject is usually the evidence itself (e.g., 'The data attest to the problem'), not a person giving an opinion.
類義語
demonstrate (More general and less formal; often used for showing something by example or experiment.)
対義語
contradict (Suggests that the evidence shows the opposite of a claim rather than supporting it.)

declare formally that something is true
To say in a serious or official way that something is true.
用法パターン：
[someone] attests that [clause]
よくある間違い：
Learners sometimes use 'attest' like 'say' in normal conversation, for example: '*He attested he was tired.*' In everyday speech, 'say' or 'claim' is better. 'Attest' is usually formal and often appears in legal, business, or official contexts, frequently followed by 'that' or 'to' (e.g., 'attest that the account is correct').
類義語
certify (Often more official or bureaucratic, especially for documents or qualifications.)
対義語
deny (Directly refuses to say that something is true, instead saying it is not true.)

witness and sign a document
To sign a paper to show you saw someone sign it, or to show it is real.
用法パターン：
[someone] attests [a document or signature]
よくある間違い：
Learners sometimes confuse this legal sense with simply 'sign.' To 'attest' a document is to sign as a witness or official, not as the main person the document is about.
類義語
witness (Common legal verb meaning to observe and sign; slightly broader and often less formal outside legal writing.)
対義語
invalidate (Means to make a document not valid or not legally effective, which is the opposite of confirming its validity.)
