Someone else's desire with 〜たがる
Grammar: Hope » 〜たがる
〜たがる describes what someone else wants to do, as read from their behavior: 行きたがる “(they) want to go”.
Japanese reserves plain 〜たい for the speaker’s own inner desire; other people’s desires are only visible from outside, and たがる marks exactly that outside view.
Usage Notes
たがる replaces the い of 〜たい: 帰
The suffix がる (“show signs of”) works the same way on emotion adjectives: 怖
