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.
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.
pure, clean, undiluted. More often used figuratively - about morals and such. Or ＊ahem＊ ethnicity.
|喫||enjoy a drink and a smoke||MOUTH||口|
|御||the honorific "o"||GO||行|
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!!!
名誉 光栄 潔さ 正直
