“Fourteenth century” is another instance of a compound adjective that appears immediately before a noun. Like all other compound adjectives in front of a noun, this one must be hyphenated. “Fourteenth-century text” is the correct form. Because “hermetically” is an adverb preceding an adjective, it does not require a hyphen.

Colons serve primarily two purposes. The first is to precede a list of three or more things in a sentence, and the second is to join two clauses of a sentence. For the first purpose, however, you should avoid using a colon after a verb or a preposition. The best way to correct the sentence above is to delete the colon.

The word "won't" is a contraction of the words "will not." The word "wont," on the other hand, is a word that means someone is likely to do something, or has a tendency to do something. In the sentence above, "wont" is correct and "won't" isn't.

Colons serve primarily two purposes. The first is to precede a list of three or more things in a sentence, and the second is to join two clauses of a sentence. The colon is missing prior to the list above, the best way to correct the underlined portion is: "here: we"

Colons serve primarily two purposes. The first is to precede a list of three or more things in a sentence, and the second is to join two clauses of a sentence where the second clause explains, defines, or clarifies the first clause. For the first purpose, however, you should avoid using a colon after a verb or a preposition. The best way to correct the sentence above is to delete the colon since it follows a verb.

Semicolons may be used to separate two related, independent clauses. Semicolons can neither follow nor precede a dependent clause, and they must be used alone, and without any accompanying conjunction. The best way to correct the underlined portion above is: "There's a lot to be done today; we all need to work together in order to accomplish everything."

Grammatically speaking, a semicolon and comma followed by a coordinating conjunction fulfill the same role in a sentence, which one you choose will depend on the context, the level of connection you wish to suggest between the content of the two sentences, and finally your personal prose style.

Quotation marks should always precede the first word of the quote, and follow the final punctuation mark of the quote; therefore, the best way to write the sentence above is "The teacher said, 'Everyone needs to turn their homework in on time, or they will not receive full credit.'"

Colons serve primarily two purposes. The first is to precede a list of three or more things in a sentence, and the second is to join two clauses of a sentence. For the second purpose, however, you may only use a colon where a period might otherwise be used, after an independent clause, and for this use of the colon the second clause should explain or define the main clause. In this case, the dependent clause directly explains the main clause, so the best way to correct the underlined portion above is, "The truth of the matter is, as always, rather simple"

When a sentence includes a list, like the list of qualities describing the mother in the example sentence, the list should be preceded by a colon, not a semicolon. Semicolons are used to separate two independent clauses within a sentence.
