WHICH WORD?
Substantiate and corroborate have similar meanings but they tend to be used with different words. Both go with claim but substantiate is also used with criticism, remark and point; corroborate is commonly used with findings, theory, results and evidence. Back sb / sth up has a similar meaning to substantiate sth, but substantiate is more formal; substantiate cannot have a person as its object. Back sb / sth up and substantiate imply that you are providing information to prove sth; bear sb / sth out and confirm sth imply that the facts are already there. * substantiate 和 corroborate 含义相近，但一般与不同的词语连用。两者都与 claim 连用，但 substantiate 还与 criticism、remark 和 point 连用，而 corroborate 通常与 findings、theory、results 和 evidence 连用。back sb / sth up 和 substantiate sth 含义相近，但 substantiate 更正式，并且 substantiate 不能以人作宾语。back sb / sth up 和 substantiate 含有提供信息以资证明之意； bear sb / sth out 和 confirm sth 含有事实已经存在之意。
