Move to my next door

Grammar Geek

So what would you say in a college essay? There's nothing informal about saying "They moved to the house next door."

 Yes, you’re absolutely right about that. However, I think we are not considering combinations of words are being used. They moved to the house next door. All of the underlined words change connotation in different orders and combinations. What is the difference between moved to and moved into? It is in realizing this that the classical and exact connotation is revealed. Also, changing the next 3 underlined words or their orders can change the connotation of the statement. What I’m trying to say is; the original statement: “My friend, Gongyou is going to move  next door.”, is quite different from "They moved to the house next door." This combination of words is valid: They moved to the house next door. This combination of words: "My friend, Gongyou, is going to move next door", is commonly used, however, invalid according to classical usage.

I agree with GG. Moved (in) next door to me.

I dont' agree that settle is an appropriate word here. We don't use settle to refer directly to moving house - it is more to do with moving area. If you moved from Number 2 to Number 4 Lilac Road, you wouldn't talk about having settled next door. You moved there.

verb
1 [I usually + adverb or preposition] to go and live somewhere, especially permanently:
After they got married, they settled in Brighton.

Are you getting this confused with the phrasal verb 'settled in'

settle in phrasal verb
to become familiar with new surroundings, such as a new house, job or school, and to feel comfortable and happy there:
Once we've settled in, you must come round for dinner.
