Question

They will come here (the/a) next week

Answer 1

They will come here next week.

Answer 2

Both "the" and "a" are grammatically correct in this context, but they slightly change the meaning of the sentence:

1. "They will come here next week." - This version uses "next week" as a specific time frame, referring to the upcoming week from the current point in time. It implies that the visit is scheduled or planned for a particular week, which is the one immediately following the present time.

2. "They will come here a week next week." - This version uses "a week next week" to refer to the week after the upcoming week. In other words, it means that they will come not in the immediate week following the current time, but the week after that.

The choice between "the" and "a" depends on the specific context and what you want to convey. If you are talking about a visit planned for the very next week after the current date, use "the." If you are referring to the week after the upcoming week, use "a."
