Questions & Answers about Jeg er enig i planen.
Norwegian usually expresses “to agree” with the phrase å være enig (literally “to be in agreement”).
- er is the present form of å være (“to be”).
- enig is an adjective meaning “in agreement”.
So Jeg er enig = “I am in agreement” = “I agree”. There is no simple verb like to agree; you always use å være + enig.
You need a preposition here; you cannot say Jeg er enig planen — that is incorrect.
With enig, Norwegian uses:
- enig i + something when you agree with an idea, plan, proposal, statement, opinion, etc.
- Jeg er enig i planen. – I agree with the plan.
- Jeg er enig i forslaget. – I agree with the proposal.
- enig med + someone when you agree with a person.
- Jeg er enig med deg. – I agree with you.
So i is required here because you’re agreeing in/with a plan (a thing), not a person.
