Both of these adjectives describe similar ideas about a person, place or thing, but there is a key difference. Fun is used to describe something that is enjoyable. example: Disney World is a fun place. In other words, when I go to Disney World I enjoy myself. Funny is used to describe something that makes you laugh. example: This book is so funny that I can’t stop laughing out loud.

Fun = 好玩儿 Funny = 幽默

Fun = enjoyable. You can also use this as a noun to mean something enjoyable: "let's have some fun!" Funny = comical. This is only an adjective.
