How do you know the difference between "very" and "too" when using muito? Or is this a bug?
I believe it's a bug. 'Muito' can mean both 'very' and 'too' and shouldn't just mean 'too'. The only word that we've learned that just means 'too' is 'de mais'. If we wanna write 'This shirt is too long' we just say 'Esta camisa é comprida de mais.
Maybe its a bug. Too means really really much, more than the necessary.
Why is it "muito" instead of "muita"? Both "camisa" and "comprida" seem to be feminine forms.
Much = muito/muita. Many = muitos/muitas. Very = muito (there is no feminine form).
Am I right in thinking:
• as "very" — it is an adbverb in that it modifies an adjective.
• as "much"/"many" — it is an adjective, so it directly modifies the noun. it must agree with the genero of the noun
Yes, it is a good way to tell them apart. Adverbs do not change! Refer to this article (in Portuguese) if you want more examples of your definition (Congrats) http://www.recantodasletras.com.br/gramatica/1763249
