She watches movies ...... at the theatre ..... every Sunday?

Question

She watches movies ...... the theatre ..... every Sunday?

Ans:

She watches movies at the theatre every Sunday.

My approach: I write this sentence as:

She watches movies at the theatre on every Sunday.

I made this because "at" is used to denote a person here for the short period of time, and "on" is used to denote days. It's a rule that we can use in the above example and also in these words like on/in the next November, on/in the next month, in/on the last month.

My question is: If the words "last", "next" and "every" are of the same type,Why they are not used with prepositions and Are there any other words I need to know about?

I found some similar sentences where no preposition was used like:

• She went home this evening.

• She went upstairs

• She went downstairs

• She went inside

• She went outside

• She went downside

• She went upside

• She went cycling

Answer 1

No! Read this.

We don't use a preposition with these words:

• next week, year, month etc
• last night, year etc
• this morning, month etc
• every day, night, years etc

and with words today, tomorrow, yesterday!

Consider the usage of "in" vs "at" with the word "theater":

In the theater here refers to the building (the theater itself). In British English, At the theater means attending a performance. However, both prepositional forms, at and in are regularly found, but in is more common with the generic term theater and at with a specific theater name.
