Quotation marks are usually used in pairs; quotation marks must be used at the beginning and end of quoted content. Use curved or "smart" quotes in word processing rather of straight quotes, which imply inches.
You are correct: quotation marks are unnecessary. The inch sign must be near to the number, putting the period at the conclusion of the full expression: 4 in. X 5 in. Please keep in mind that the sign for inches is the double prime (""), not the double quotation marks (""), straight quotation marks (""), or (gasp!) apostrophe (').
Quotation marks, either double ("") or single (""), are commonly used for direct quotes, titles, and words used in a certain way. Quotation marks are usually used in pairs, one at the beginning and one at the conclusion of the cited text. The same logic applies to titles and phrases used in a certain context or to emphasize something. For example, Mr. Smith's letter is an example of a direct quote because it was taken word-for-word from another document; in this case, the quoted material is actually part of the original letter.
The use of quotation marks is important in journalism and other forms of writing that involve quoting people. If someone is quoted accurately but incompletely, then they may be able to claim that what you said wasn't true. For example, if I were to say "Mr. Smith has been convicted of fraud" and omit the fact that he has yet to be sentenced, then I would have committed plagiarism. To avoid this problem, journalists should always include all relevant information when quoting someone.
In general, quotation marks are not needed for indirect quotes, which are quotations that aren't attributed to a specific source. Indirect quotes can be difficult to identify since they don't contain any quotation marks. Instead, they are identified by including the name of the person who said it in parentheses following the quoted text. For example, "John said that Joe did not like carrots" is an indirect quote because it contains no actual quotes from anyone else.
We use quote marks to indicate (or mark) the beginning and conclusion of a term or phrase that is unique or comes from somewhere other than the text that we are composing. The use of double (".") or single (".") quotation marks is a matter of preference (see below for more information).
A term or phrase in quotes is called a "quoted term". A quoted term may be in capital or small letters depending on how it is marked within the source document. Capitalized terms are considered separate words and are treated differently by most word processing programs. For example, if you wanted to write that John is "a teacher like Jesus", the program will interpret this as two words instead of one: "John is a teacher like Jesus".
If you want to include the entire sentence in which the term appears, start with a pair of single quotation marks. For example, "He said, 'I'm going fishing.' " Would result in the term "he said" being interpreted as one word instead of two. To include the whole sentence, begin with no quotation marks at all, like this: He said, I'm going fishing.
In this case, the quotation marks are used to identify a word that is unique to the text and should not be interpreted when searching for other instances of the word within the document.
Quotation marks indicate which words are part of a dialogue or something uttered by someone. They indicate when someone is speaking. Quotation marks are used in pairs to divide a quotation from the rest of the writing; they are used at the beginning and end of a quote to distinguish it from the rest of the text. For example, "I like apples" and "Apples are good!"
Using quotation marks when writing about children or young people can be difficult because these subjects are real and not fiction, so they cannot be omitted. However, when writing about their actions or comments, you can remove these marks because they are not part of their actual speech.
For example, "Eliot responds to the question 'Why do we use quotation marks?' with an explanation that quotes other scholars." Or, "Evan laughs when I ask him if he knows why we use quotation marks."
Even though quotation marks are used when discussing children's issues because they are not able to give consent, they are still included in this article because they are a part of the academic conversation.
Spacing. The usual rule is that no space should be placed between the quote mark and the following word, nor should a space be used between the final word and the closing quotation mark. However, some writers do place a space after the quotation mark.
