why is this wrong?


this paper is about the importance of the flu vaccine. Below is the sentence in which Grammarly says is wrong. The flu comes in 3 types: A, B, and C. Is there a better way I should have written this?

See example:

of viruses; types A, B, and C. Every one of these types are further ...

Your example shows parts of two sentences, so it is difficult to make a guess about the problem.  Can you show us the complete sentence in question?

You have written a longer text in your question: The flu comes in 3 types: A, B, and C.  Then, in the "see example" italicized section, you excerpt a small portion of the text, but with wording and punctuation differences: of viruses; types A, B, and C. Every one of these types are further ....  So, as Patty has already said, your question is quite confusing.


The use of the colon in the first example is correct; the use of the semicolon in the second excerpt is incorrect.  You must use a colon, not a semicolon, to introduce a list.


Avoid using the casual word the flu if, as it appears, this is an academic essay: use the formal term influenza (not the influenza) instead.  You also need to change the wording so as to avoid the phrasal verb come in.  That verb is only appropriate for products, not diseases.  From what I can deduce from the second excerpt, perhaps you have already made that change.

Sorry, Sanjay, but that doesn't make any sense at all.
