介 introduce / intervene

I'm going to introduce you to mr. Kai, the KITE maker.

I know it's peaked roof plus '8', but you can think of this as an arrow pointing at the person you are introducing, a la the coveted "I'M WITH STUPID" shirt.

introduce ★★★☆☆
紹 (acquaint) + 介 (introduce / intervene) = 紹介 (introduce )

introduce (someone or something to somebody else)

introduce yourself to a group. ★★☆☆☆
自己 (one's own) + 紹介 (introduce ) = 自己紹介 (introduce yourself to a group.)

hard to deal with ★★☆☆☆ 1/2 KANA
厄 (misfortune) + 介 (introduce / intervene) = 厄介 (hard to deal with)

troublesome, worrying. Hard to deal with! A hard-to-fix appliance. A stubborn, persnicketty person.

intervention ★☆☆☆☆ NP
介 (introduce / intervene) + 入 (put/go in) = 介入 (intervention)
