went through と experience 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。

went through is an informal way of saying experience.

"he went through a lot"

"he experienced a lot"

same meaning. "experienced" just feels more formal.

experience can also be used as an adjective or noun to mean wisdom/to be wise. you can't do this with "went through"

"he was very experienced."
(he was very wise)

"he was very went through"
