吝啬-ness
Now those are characters I haven't seen in a while lol.

one of the equivalents of the お/ご prefix, basically?), but a rather unique if not-too-common use is 贵人 for someone who's helped you greatly and not necessarily in the material sense.
useful way to think of it! (I went looking for 贵人 in Guardian and found the student who sells Zhao Yunlan her old books using it to praise him, little does she know.)
