'She states that it is so' was accepted today. I think that 'She says yes' is another possibility.
Assert has a slightly different meaning to confirm. Confirm means to give the affirmative, to state that something is true. Assert means to defend that something is true. From www.thefreedictionary.com/assert 1. To state or express positively; affirm: asserted his innocence. 2. To defend or maintain (one's rights, for example).
Although your answer could certainly be considered correct, as it is given in the list of translations.
"Afimar" looks like "affirm" in English to me, and "affirm" is similar to "assert", I guess that's why it's confusing... Thank you very much for your help.
Keep in mind that affirm, assert and confirm are synonyms (they have similar meanings) however confirm is used in quite a different way to assert and affirm (which are used in very similar ways).
I know! I wrote "she affirms so," but then when I saw it wasn't one of the translations, I changed it to "she asserts so," which they marked as incorrect!!
Also, "asserts" was the required translation of "afirma" in an earlier sentence.
So would this sentence mean in English, "She is stating the word yes" or "She confirms it" ? Or no difference?
