There is a difference between US and British/Canadian punctuation styles.
In the US
Trailing periods and commas always appear inside the quotation marks
ex. "Let's go to the zoo."
ex. The spelling of the word is "ampersand." - He said, "Go now," and turned away.
But question marks follow the same logic logic as below.
In the UK and Canada
The punctuation follows the logical extension of the quote.
The period or comma goes outside the quotation mark, except where the period is part of a quote.
ex. He said "The day is long." - The movie was called "Benji".
In either version of English
If you are quoting a question then the ? will go within the quotation marks.
ex. Sally asked, "Where are you going?"
If you're asking a question about a quote, then the ? will go after the quotation marks.
ex. Did Sally say, "We are going to the zoo"?
Note: There is never any double punctuation used.
In American (U.S.) style periods always come before closing quotation marks.
Ex.
He said, "I liked the movie very much."
In British style, it depends. If the period appeared in the original quote, then it is placed before the closing quotation mark, the same as the American style. If the period did not appear in the original quote, it is placed after the closing quotation mark. The same rules apply for commas but not semicolons.
British style places commas and periods that are not part of the quoted material outside of the quotation marks. Also, in technical applications or when discussing coding, punctuation that is not part of a text string should be placed outside of the quotes. Placing commas and periods inside the quotes implies that they are part of the string to be displayed.
If the period is part of the quote, it goes inside the closing quotation mark. If the period is not part of the original quote but is part of your sentence, it goes outside the closing quotation mark.
Most of the time the answer is yes. Sometimes, you can end a quote at the end of a sentence using the ellipsis or the (...). For example, the court stated that even the the Defendant was wrong, she should not "pay retribution persuant to the contract..." Notice that even here the quote is after the period.
do quotation mark go before or after period
It comes after. The full-stop (or period) indicates the end of the sentence.
Quotation marks go after the period in a sentence. She said, "I have to go now."
The period should go inside the quotes.
After
It will be placed at the end of the sentence iand after the parenthesis. It will define that the sentence is concluded
It always goes at the end of the sentence. It may seem counter-intuitive, but that is according to the MLA guidelines. Also, the period goes before the number as demonstrated here (123).
Right before the quote ends. For example:He said, "You are a jerk."
Quotations should go after the period at the end of the sentence when copying a sentence from a book.
Parenthesis go before the period. The period signals the end of the sentence.
Commas do not go at the end of sentences. Periods go at the end of sentences. Generally when typing on a computer, you should have two spaces after the period at the end of a sentence.
after
Outside. (But if the entire sentence is a parenthetical like this one, it would go inside.)
Use a period to end the final sentence within the parenthetical, then use a period outside of the parenthetical to close the sentence in which the parenthetical takes place.
after the quotation marks because if put before the quotation mark, that makes the quote seem like if it continues after what you wrote even if the quote has ended. period marks go before the quotation mark because that is ending a sentence... period.
A period does come before a quotation mark if the quotation at the end of the sentence, such as:Lucy than said, "Hi, Mr. Warner."If the quotation is not at the end of the sentence, use a comma instead of a period, such as:"Hi, Mr. Warner," Lucy replied.
In general, the period goes within the parentheses (I really wasn't sure it was a good idea.) My paranthetical sentence was just an example ... but I am not sure what you mean by imcomplete thought...... then you would end with ...
