"Wit" is really old English for the general activity of the mind. It includes intelligence, but also perception and cleverness, and the ability to act on ideas. The word is rarely used in modern English with this meaning. The modern meaning of "wit" is "funny". Intelligence is only one aspect of the mind.

there is a subtle difference between intelligence, wit and wisdom. wisdom often suggests age - you would rarely hear a youngster being referred to as possessing wisdom, it's something you gain as you get older. 'wit' has two meanings - to be mentally sharp but also refers to a sense of humour. example - the comedian was very witty. (the comedian was very funny). he / she has wits about him / her (they are sharp / intelligent).

Wit implies being quick and sharp. Wisdom implies experience and understanding.

Wisdom is a general intelligent, someone who is wise may know a lot of things about various people, places and so on. Some Americans would refer to this as "book smart". If someone refers to you as wise, you're seen as intelligent. Wit is more so cleverness. If someone calls you witty, they're referring to you as clever, humorous even, able to understand and perceive things quickly~ :)
