攵, "Boku," is on the right. This radical is a pictogram of a hand breaking something with a stick.
The part on the left (苟) apparently bears no relation to the kanji 苟, which means "any". No relation, even though they look identical. The 苟-looking piece of 敬 combines person, horns, and a mouth. Kanji Networks says it's like going stiff when faced by a charging ram, thus stiffness, formality.
Whatever. We're going to remember this kanji by thinking this way: "If 苟 (any) student is rude, he gets 攵 (the stick). That's how you teach respect."
敬語. Keigo. It's an important thing, in Japanese. Too bad it doubles our work as learners. You have to learn new rules, new vocabulary, new kanji. All of my teachers have always put keigo off until, say, Intermediate II level. By then, it's too late. We've already practiced and practiced with the neutral or (a little bit) casual expressions.
I think keigo should be taught right away, alongside normal speech. I'm still struggling with keigo these days, and I wish I'd learned it earlier.
