The word 'brainy' is used to describe someone who is very intelligent or smart. It is often used in a positive way to compliment someone who is very good at thinking and solving problems. For example, you could say "My friend is very brainy, she always gets top marks in her exams" or "I wish I could be as brainy as my teacher". However, it's important to remember that not everyone likes to be called 'brainy', as they may feel it puts pressure on them to always be perfect. So, it's best to use the word in appropriate situations, like when you want to praise someone's intelligence.
