Synonym Chooser
Some common synonyms of substantiate are authenticate, confirm, corroborate, validate, and verify. While all these words mean "to attest to the truth or validity of something," substantiate implies the offering of evidence that sustains the contention.
Although the words authenticate and substantiate have much in common, authenticate implies establishing genuineness by adducing legal or official documents or expert opinion.
The meanings of confirm and substantiate largely overlap; however, confirm implies the removing of doubts by an authoritative statement or indisputable fact.
While the synonyms corroborate and substantiate are close in meaning, corroborate suggests the strengthening of what is already partly established.
While in some cases nearly identical to substantiate, validate implies establishing validity by authoritative affirmation or by factual proof.
The words verify and substantiate can be used in similar contexts, but verify implies the establishing of correspondence of actual facts or details with those proposed or guessed at.
