~たがる (want to, third-person)
grammar32 sentences
The third-person desire suffix ~たがる attached to a verb stem — 'X wants to (as observed from outside).' Used when reporting someone else's wanting, since ~たい is restricted to first-person assertion in plain speech. Reflects the convention that you can't directly assert another person's feelings — only their visible signs. Built from ~たい + ~がる.
