A journal is a record of thoughts and events that are important to the writer.
Many English words have Latin or Greek parts. For example, the Latin prefix com- means with or together. It appears in words like companion and connect.
A topic is what a piece of writing is about. The main idea is the most important idea about the topic. Think about the overall idea of a paragraph, section, or an article. Supporting details give small pieces of information about the main idea.
Good readers use the text structure, or the way text is organized, to help them understand what they read. For example, a nonfiction article may compare and contrast two things, put events in sequence, or be a series of clear main ideas.
