Relation
Noun, する verb, and の adjective
かんけい
ビエトはヤクザだが、そのはんざいには関係してないとだん言できます。
Viet is a yakuza, but I can say for sure that he is not connected to that crime.
ビエトは、ヤクザとの関係をたってトーフグの仕事に専念するかどうかまよっています。
Viet is wondering if he should cut his connections with the yakuza and just focus on his work at Tofugu.
「彼は前に結婚していて、子供も3人もいるのよ。」「知ってるわよ。でも、それとこれとは関係ないでしょ。」
"He’s been married before and has three kids." "I know, but that has nothing to do with it."
A connection related to another connection obviously has some kind of connection, at least between all those meanings.
This is a jukugo word, which usually means on'yomi readings from the kanji. If you know the readings of your kanji you'll know how to read this as well.
