wise と clever と intelligent と smart はどう違いますか？説明が難しい場合は、例文を教えて下さい。

Intelligent is the easiest of these words and one applies the word to refer to a person having thinking and analyzing ability.
Clever is a word that is used for people (mostly for animals such as dogs) who can think of alternative ways to wriggle out of a tough situation.
Wise is a word that connotes a person who has a lot of knowledge and wisdom.
Smart is very close to intelligence though these days it has come to be associated with physical appearance. Smart is also well dressed. It is less formal than intelligent.
