For example. If I want to quote a passage from a writing, that says
The cake is not a lie.
and my sentence is:
The book by author states that "The cake is not a lie." however studies show that the cake is a lie.
Is it OK to replace the period with a comma to make the sentence flow?
Relevant: Also what do you do with the capital "T" Are you allowed to lowercase it?
The book by author states "the cake is not a lie," however studies show that the cake is a lie.
I usually just work around this by switching up the structure of the sentence, but sometimes I really want to phrase something a particular way.
