Certainly. (where appropriate)
Parentheses go before the period in a sentence. If the entire sentence is contained within the parentheses, then the period goes inside. However, if the parentheses are used to add information or clarification within a larger sentence, the period should be placed outside the closing parenthesis.
Outside. (But if the entire sentence is a parenthetical like this one, it would go inside.)
(If it adds clarity) one may start a sentence with parentheses.
A period would go inside parentheses to finish a complete sentence, but you always need sentence-ending punctuation outside of the parentheses.
A comma typically goes before parentheses if the sentence structure requires it. For example, in the sentence "She decided to go to the park (which was quite crowded), despite the weather," the comma is placed before the parentheses. However, if the parentheses are at the end of a sentence and the sentence does not require a comma, then no comma is needed.
The entire sentence should be in parentheses, however the portion that is, should contain a period outside of the parentheses.
Parentheses are placed at the end of a sentence before the final punctuation mark. If the entire sentence is within the parentheses, the period goes inside the closing parenthesis. For example: "He bought apples (which were on sale)." If the parentheses contain a complete sentence, the period should be placed inside the closing parentheses.
Parentheses go before the period in a sentence. If the entire sentence is contained within the parentheses, then the period goes inside. However, if the parentheses are used to add information or clarification within a larger sentence, the period should be placed outside the closing parenthesis.
Whether a question mark goes inside parentheses depends on the context of the sentence. If the entire sentence within the parentheses is a question, then the question mark should be inside. However, if the main sentence is a question but the content in the parentheses is not, the question mark remains outside. For example: "Did you see the movie (was it good)?"
A period should be placed outside the parentheses if the entire sentence is contained within the parentheses. However, if the parentheses contain a complete sentence that stands alone, the period should be placed inside. For example: "He went to the store (which was closed)." Here, the period is outside the parentheses.
Outside. (But if the entire sentence is a parenthetical like this one, it would go inside.)
Depends! (If the sentence starts and ends inside the brackets the punctuation does too.) If the sentence is part in (and part out) the punctuation goes outside the brackets. It is the same with quotation marks (look in a newspaper and you'll see what I mean).
(If it adds clarity) one may start a sentence with parentheses.
Periods should typically go on the outside of parentheses. However, if the entire sentence is contained within the parentheses, then the period should go inside.
The end punctuation in a sentence with parentheses depends on the overall sentence structure. If the parentheses contain a complete sentence, the period goes inside the closing parenthesis. If the information in the parentheses is additional or clarifying, the ending punctuation goes outside the closing parenthesis.
A period would go inside parentheses to finish a complete sentence, but you always need sentence-ending punctuation outside of the parentheses.
In American English, periods typically go inside parentheses when the parenthetical phrase is a complete sentence. In British English, periods go outside parentheses unless they are part of the parenthetical sentence.
