Notes

Similar
たがる is がる bolted onto たい's stem — the same externalizing move; plain がる rides emotion adjectives (怖がる・嫌がる), たがる covers wanting-to-act.
Lookalikes
One kana apart in the past (行きたかった/行きたがった), but たい asserts the speaker's own urge while plain third-person desire requires たがる — which also prefers を where たい leans on が.
