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