Restraint
Decline, Hesitation
noun, する verb, な adjective
A far consider is when you let your considerations go far from you so you don't think about how angry you are about what's going on in front of you. It allows you to have some restraint, since your considerations are far from here. It also allows you to decline things, since you're not considering the other person's feelings.
えんりょ
This is a jukugo word that uses the on'yomi readings of the kanji. You've learned them both already, so you should be able to read this on your own.
