[Are they all correct? Would you check the position of 'often'?]

All are correct, but 1 is the best, and 3 is next best.

Remember to keep adverbs as close to whatever they're modifying as possible, just as you should do with adverbs. This goes for adverbial and adjectival phrases and clauses.

Yes, all three sentences are grammatically correct. The positions of "often" vary in each sentence, but they are all acceptable.

In sentence 1, "often" is placed immediately before the verb "goes." This is a common placement for an adverb of frequency like "often."

In sentence 2, "often" is positioned at the beginning of the sentence, before the subject "he." While this placement is less common, it is still grammatically correct and emphasizes the frequency of going to the movies.

In sentence 3, "often" is positioned at the end of the sentence. This placement is also commonly used, particularly when there is a desire to emphasize the frequency at the end of the statement.

Overall, the choice of where to place "often" depends on the desired emphasis and style of the sentence, but all three options are grammatically correct.
