What you will learn about Grammar and Punctuation Refresher
The 7-day sprint
- The Clause Is the Building Block. Every sentence is built from clauses, and a clause is a subject paired with a verb that says something about it.
- Where One Sentence Ends. A period, semicolon, comma-plus-conjunction, or subordinating word is what legally separates two independent clauses; a bare comma is not.
- The Four Jobs of the Comma. Commas separate items in a series, close off an introductory element, fence off information the sentence does not need, and join two independent clauses when a coordinating conjunction is present.
- Semicolons, Colons, Dashes, and Parentheses. Each of these marks signals a specific relationship between parts of a sentence, and picking the right one is about relationship, not about emphasis.
- Apostrophes Do Only Two Things. An apostrophe marks possession or shows that letters have been omitted, and it never makes a word plural.
- Agreement and Pronouns. Verbs must match their real subject in number, and every pronoun must point unambiguously to one noun.
- Placement, Parallelism, and a Real Proofreading Pass. Sentences read clearly when modifiers sit beside what they modify, listed items share the same grammatical shape, and you edit in targeted passes rather than all at once.
