Is there a formal and an informal way to say it?
Legal is informal. If you want to use a colloquial synonym, you might use bacana to mean 'cool' or 'great'. To express something is 'awesome' or 'neat', younger speakers often use maneiro. In Brazil, the idiomatic expression da hora is also used to describe something cool or enjoyable. The word Interessante can convey a sense of something being cool or unique.
Is it said differently in some regions?
In Portugal, the word fixe is used to mean 'cool'.
How does it change in a sentence?
The adjective legal is invariable for gender and remains legal whether describing a masculine or feminine noun. However, it must agree in number with the noun it modifies, changing to legais for plural nouns.
How do you pronounce it?
/leˈɡaw/
