When you add sugar to it, your cup of coffee becomes not only sweet, also fattening.
Which word used incorrectly in the sentence?
The answer: is becomes.
But there is a bit off about where "also" after the comma. I think it should be "not only..., but also"
And should "becomes" placed behind "not only"?
Please, someone help me. Thank you!
The verb "becomes" is correct in that sentence. (I don't see "is becomes" there.)
Also, "not only" is placed correctly, after the verb. I agree with you that "but also" is the correct wording.

You are correct in noticing the incorrect usage in the sentence. The word "becomes" should be placed after "not only," and the correct phrase should be "not only sweet but also fattening." The corrected sentence would be:
"When you add sugar to it, your cup of coffee becomes not only sweet but also fattening."
Yes, you're right to question the placement of "also" in the sentence. The correct construction is indeed "not only... but also." This structure is used to emphasize two different qualities or effects of something.
To correct the sentence, you could say: "When you add sugar to it, your cup of coffee not only becomes sweet but also fattening."
In this revised sentence, "not only" comes before "becomes," and "but also" emphasizes the second quality or effect, which is "fattening." This format accurately conveys that the coffee is both sweet and fattening when sugar is added.
