潔 (Kanji for honorable)

Onyomi

KETSU

OK, the "enjoy a drink" kanji is a bit simplified - it's MISSING the 口 radical! If you can get past that, then you can use this mnemonic:

The honorable person enjoys a drink of KETCHUP or water instead of booze.

いさぎよ*い	honorable - unlike the related term 名誉（めいよ）　潔さ happens even if no one is looking. 潔さ means someone who puts principle above everything else - someone who will turn down a job offer from a mob-connected business, even if they are really broke and don't have enough to eat. This is also the word used about guys who commit suicide for honor. CCW ★☆☆☆☆
いさぎよ＊さ	honor ★★☆☆☆

清潔(せいけつ) な

pure ★★☆☆☆
清 (pure) + 潔 (honorable) = 清潔 (pure)

pure, clean, undiluted. More often used figuratively - about morals and such. Or ＊ahem＊ ethnicity.

不潔(ふけつ) な

filthy ☆☆☆☆☆
不 (un) + 潔 (honorable) = 不潔 (filthy)

I'm free TODAY, to enjoy a drink with my MOUTH.

I'm honorable so I'll share my WATER .

As for 御, it is easy because the left radical means GO in English, and it's pronounced GO!!!
