No, a poison ring is a giftring, without the e. Don’t know why.

In Norwegian same thing: giftering, “the state of being married-ring”. Jeg er gift = i am married. It also means “I am poison”, though.

One of the best moments I had when I walked around Mont Blanc was when we came to a col on a foggy day and passed a group of Japanese tourists just as the fog lifted and you could see the fantastic view. They burst out oh and an-ing snd even laughing while they thanked the relieved guide.
