Question

If I finish a sentence with a bracket should the full stop be inside or outside the bracket? For example, is it .) or ).

Answer 1

Outside the bracket, every time.

Explanation:

In the example you give, you are using parentheses, not brackets. Either way, though, the full stop belongs outside.

Parentheses bookend a word or clause that can be removed from the sentence and it will still make perfect sense; putting the period, question mark, etc. inside leaves you with no indication that the sentence ends, just the parenthetical.

Brackets indicate that (within a quote) someone other than the speaker is inserting a comment, or (within any other text) that someone other than the author is commenting, perhaps an editor or moderator. Either way, you still need a full stop outside those brackets.
