I'm banking on these being 100% correct per logical (or British) punctuation. Do you agree with me?
1. I don't like the saying 'Absence makes the heart grow fonder'.
(Full stop outside the ending quote mark as shown because this is not a direct quote from somebody? - AGREE)
2. I loved your sentence 'John had been besieged by apoplexy'.
(Full stop outside the ending quote mark as shown because this is not a direct quote from somebody? - THIS IS OKAY, BUT FULL STOP COULD BE INSIDE TOO AS IT FEATURES IN THE ORIGINAL. THERE'S A LOT OF LENIENCY ON THIS RULING.)
3. John said, "I heard Mike say, 'I am running for student council next year'."
(Ending punctuation correct? I say yes, per British style.) OKAY, BUT FULL STOP COULD BE INSIDE THE SINGLE QUOTATION TOO AS IT FEATURES IN THE ORIGINAL.
4. Mike said, 'I am running for student council next year.'
(Period goes inside in this one because it's a direct quote, correct?) GOOD
5. 'I will,' Mike said, 'run for student council next year.'
(Correct as punctuated? I think so.) THIS IS U.S. CONVENTION. COMMA SHOULD E OUTSIDE FOR U.K.
6. I didn't appreciate it when she said, "I think you're a tad shady".
(I'm repeating what I heard her say; thus, the full stop falls outside the ending quote marks as written above - good?) YOU'D GET AWAY WITH IT INSIDE TOO.
7. "I didn't appreciate it when she said, 'I think you're a tad shady'."
(In this one, per British style, I believe the ending punctuation is '."
Do you agree?) THE ENDING .'" COULD ALSO WORK.
The idea that punctuation which featured in the original ought to go inside leaves room for interpretation. Bottom line: be consistent.
