"I do not remember her name."
Translation:Non ricordo il suo nome.
hmmm. why is Non ricordo suo nome' marked wrong?
Mukapazza posted earlier the three rules where you need to use the article (plural nouns, modified nouns, and 'loro' nouns. None of the three rules seem to apply here, so I left out the 'il' and wrote 'Non ricordo suo nome' and was marked wrong.
(edit) as f. formica kindly points out below, the pronoun needs to be used here (because it is not a close family relationship like 'sua sorella'), and the three rules I list above are exceptions to the close fam. relationship rule.
