type
The Italian word 'tipo' can be used in the same contexts as 'type' in English. It is used to refer to a category of something, the form or character of something, or a particular kind or class. However, 'tipo' can also take on a colloquial use not present in the English 'type', where it refers to a person in a somewhat informal manner, vaguely similar to 'guy' or 'dude' in English slang.
