Summary: Four Principal Sentence Structures

Structure, Clause composition, Example

1. Simple: One independent clause, She studies physics.

2. Compound: Two or more independent clauses, She studies physics, and he studies chemistry.

3. Complex: One independent clause and at least one dependent clause, She studies physics because she enjoys science.

4. Compound-complex: At least two independent clauses and at least one dependent clause, She studies physics because she enjoys science, and he studies chemistry.

Recommended learning sequence: Begin with sentence elements and basic patterns (Topics 1–3), master the four principal sentence structures (Topics 4–8), study phrases, clauses, and word order (Topics 9–16), then progress to transformation, advanced syntax, and academic writing (Topics 17–40).

This syllabus contains 40 major topic areas covering foundational, intermediate, advanced, and academic sentence structures in English grammar.
