Translation:Our neighbors are getting settled in their new house.
Our neighbours are settling into their new house. 'Settling down in their new house' is not something i have ever heard anyone say.
Can someone exolain why the word 'install' does not have the nous ending of 'ons'?
The subject is "our neighbors/nos voisins" or "they/ils/elles" are getting settled into their new house (third person plural). "We/nous" is not the subject of the sentence.
