It was_that arrived at the same home
Answers
Explanation:
Home is a noun, an adjective and a verb.
When we use home as an adjective, we do not use preposition but when we use home as a noun, we use preposition. When any possessive adjective comes before home, you apply a preposition. The reason is after possessive adjective, we use a noun. Here, home works as a noun and we put a preposition.
Arrive home and arrive at home both have the same fundamental significance. Use of at home gives stress on the location while home without preposition describes the person's state of being in a place where he lives.
Remember it!
At home is also a phrase. It means proficient.
Example:
Susana Crispens Nosek is at home in Philosophy of law.
This is the main reason, most of the people use home without at and it behaves as an adverb.
