I understand that the partative article is used for uncountable amounts. e.g. 'je mange des pâtes'. It is clear that pasta is never going to be counted, so it makes sense it would be partative des.
However if i say 'je mange des carottes', I could mean a big plate of chopped up carrots which are uncountable, which would be partative des.
Or I could mean I am eating 3 whole carrots which are definitely countable. So would this be indefinite des?
Is it the context that would define which article is used?
