Is coming and next the same meaning?

Answer 1

In some uses they are. "This coming week" and "Next week" mean the same thing (usually).

However, you wouldn't use "next" in this sentence:

"Your grandparents are coming to dinner."

or this:

"Watch this space for coming events."

You couldn't use "coming" in this sentence:

"After waiting an hour, I am finally next in line."

or this:

"The next time we go into the city, I want to eat at the new French restaurant."

Answer 2

Yes, "coming" and "next" can have similar meanings when referring to future events or time sequences. "Coming" implies the event is approaching or about to happen, while "next" denotes the event that follows in a sequence or order.
