Questions & Answers about As televisões são muito caras.
How do we know to use televisões instead of televisãos?
Why is it As televisões? Doesn't the -ão ending usually mean a word is masculine?
Why doesn't the word muito change to match the feminine plural caras?
In this sentence, muito means "very" and describes how expensive they are. When it is used to mean "very", it acts as an adverb and its form never changes. It only changes to muita, muitos, or muitas when it describes a noun, meaning "much" or "many" (for example, muitas televisões would mean "many televisions").
Why do we use são instead of estão?
