To Invite, To Raise, To Grow Violent, To Become Stronger
intransitive verb, transitive verb, godan verb
The kanji is recruit so the verb vocab version would, you'd think, be 'to recruit,' but it's to appeal for or to invite or to raise. So, it's kind of like recruiting, but instead of people, you're recruiting for things and actions.
This verb can also be intransitive (oh my!) and mean to grow violent or to become stronger. It's like all of that recruiting is happening inside of you and causing some weird things to happen to you!
You'd like to appeal fortwo, no (つの), three things! Three!
