How useful:
2. to be for someone, to turn out for someone ("jemandem ergehen" - Someone poetic word for the idea of how someone was/is/will be faring. Think of meeting someone after 6 months. It's only used in books though and sounds old school. And it's hard to use anyway. )
How useful:
3. to be passed, to be issued (For laws and certain orders. Sounds VERY formal and you do not hear this word in daily life. The law or regulation is the subject.)
How useful:
4. to indulge in, to get lost on ("sich+Acc ergehen in+Acc" - ONLY for figurative contexts like indulging in platitudes or dreams. Very rare. I never hear it in daily life, except a couple of fixed phrasings.)
How useful:
5. to endure something, to submit to something ("etwas über sich+Acc ergehen lassen" - literally to let something "go over" you. Think of a thorough pet down at the airport for example. This phrasing is fairly common in daily life. )
