❓ Frequently Asked Questions
Q1.What is a comma splice and how do I fix it?▼
A comma splice is when you join two independent clauses with only a comma (e.g., 'I like coffee, she likes tea.'). Fix it with a period, semicolon, or conjunction (and/but/or).
Q2.When do I use 'its' vs 'it's'?▼
'Its' shows possession (The dog lost its bone). 'It's' is a contraction of 'it is' or 'it has' (It's raining).
Q3.Do I put punctuation inside or outside quotation marks?▼
In American English, periods and commas go inside quotation marks. In British English, they can go outside unless part of the quoted material.
