Grammar has two main parts: words and structure. Structure involves how we put words together to form phrase, clauses, and sentences. **Parts of Speech** - All words in a language belong to a category called a part of speech. (see [Parts of Speech](../figs-partsofspeech/01.md)) **Sentences** - When we speak, we organize our thoughts in sentences. A sentence usually has a complete thought about an event or a situation or state of being. (see [Sentence Structure](../figs-sentences/01.md)) * Sentences can be statements, questions, commands, or exclamations. (see [Exclamations](../figs-sentencetypes/01.md)) * Sentences can have more than one clause. (see [Sentence Structure](../figs-sentences/01.md)) * Some languages have both active and passive sentences. (see [Active or Passive](../figs-activepassive/01.md)) **Possession** - This shows that there is a relationship between two nouns. In English it is marked with "of" as in "the love of God," or with "'s" as in "God's love," or with a possessive pronoun as in "his love." (see [Possession](../figs-possession/01.md)) **Quotations** - A quotation is a report of what someone else has said. * Quotations normally have two parts: Information about who said something and what the person said. (see [Quotations and Quote Margins](../writing-quotations/01.md)) * Quotations can be either direct quotes or indirect quotes. (see [Direct and Indirect Quotations](../figs-quotations/01.md)) * Quotes can have quotes within them. (see [Quotes within Quotes](../figs-quotesinquotes/01.md)) * Quotes can be marked to make it easy for readers to understand who said what. (see [Quote Markings](../figs-quotemarks/01.md))
