Introduction to Grammar

Grammar is the system of patterns that lets words combine into meaningful clauses and sentences. It helps readers predict relationships and writers control emphasis. Some rules describe widespread usage; others are conventions expected in formal contexts. Effective grammar depends on audience, purpose, dialect, and register.

Patterns and examples

• The children are playing outside. (standard agreement and aspect)
• Could you open the window? (question form used as a polite request)

Notice how form and meaning work together. Read examples aloud, identify the controlling word or clause, and compare them with nearby alternatives before applying the pattern in new writing.

Practice sentences

• Identify the subject and complete verb in: The old bridge has been repaired.
• Rewrite an informal message for a formal audience.

After answering, explain the rule in your own words and create one original sentence using the same structure.
