Adverb Sometimes


The position of “sometimes” in these sentences is correct in grammar?

1.I get up sometimes at seven.
2.I sometimes get up at seven.
3.Sometimes I get up at seven.
4.I get up at seven sometimes.


2 is the “standard” position.
3 + 4 are common alternatives.
1 is not typical or usual, so I’d advise against using it.
