Should I change the structure of a sentence/add filler words to make sure that the sentence always starts with a capital letter?
As a concrete example, imagine that I'm talking about prepositions, and I want to say that the word "with" is okay to use. I gather that when quoting a word, I can use either quotation marks or italic font, but I'm confused about capitalization at the beginning of the sentence. For example:
- with is always okay.
- With is always okay.
- "with" is always okay.
- "With" is always okay.
Which is correct?
I'm guessing #2 and #4, with the capitals, but my logical side does not like the capital letter getting inside the quotation, since it is not really part of it.
