5.2 Sentence structure

Sentence structure forms the backbone of effective communication in English. It encompasses elements like subjects, predicates, and clauses, which combine to create various types of sentences. Understanding these components is crucial for crafting clear, coherent writing.

Mastering sentence structure enhances both reading comprehension and writing proficiency. It allows writers to express complex ideas, create emphasis, and maintain reader engagement. By varying sentence types and patterns, writers can develop a more sophisticated and impactful writing style.

Elements of sentences

• Sentence structure forms the foundation of effective communication in English language arts
• Understanding sentence elements enables students to craft clear, coherent, and grammatically correct writing
• Mastery of sentence elements enhances both reading comprehension and writing proficiency

Subjects and predicates

• Subject represents the doer or main focus of the sentence
• Predicate contains the verb and provides information about the subject
• Simple subjects consist of a single word or phrase (The energetic puppy)
• Complete subjects include all words that modify the simple subject (The energetic puppy with the wagging tail)
• Simple predicates contain only the main verb or verb phrase (barked loudly)
• Complete predicates encompass the verb and all its modifiers (barked loudly at the passing mailman)

Clauses vs phrases

• Clauses contain a subject and a predicate, forming a complete thought
• Phrases lack either a subject or a predicate, or both
• Noun phrases function as nouns in a sentence (The old red barn)
• Verb phrases consist of a main verb and its auxiliaries (had been running)
• Prepositional phrases begin with a preposition and end with a noun or pronoun (under the table)
• Participial phrases contain a participle and function as adjectives (Exhausted from the long hike)

Independent vs dependent clauses

• Independent clauses express a complete thought and can stand alone as sentences
• Dependent clauses rely on independent clauses to form complete sentences
• Subordinating conjunctions introduce dependent clauses (because, although, while)
• Relative pronouns also introduce dependent clauses (who, which, that)
• Dependent clauses function as nouns, adjectives, or adverbs in sentences
• Combining independent and dependent clauses creates complex sentence structures

Types of sentences

• Sentence types provide variety and complexity in writing and speech
• Understanding different sentence structures allows for more sophisticated expression of ideas
• Mastering various sentence types enhances overall writing quality and readability

Simple sentences

• Contain one independent clause with a subject and predicate
• Express a single, complete thought
• Can include compound subjects or compound predicates
• Often used for emphasis or to convey straightforward information
• Vary in length from very short to quite long (The cat sleeps)
• Can include modifiers and phrases to add detail (The sleek black cat sleeps peacefully on the windowsill)

Compound sentences

• Consist of two or more independent clauses joined by coordinating conjunctions
• Use coordinating conjunctions (FANBOYS: for, and, nor, but, or, yet, so)
• Can be connected with semicolons instead of conjunctions
• Express related ideas of equal importance
• Allow for more complex expression of thoughts
• Require proper punctuation to avoid run-on sentences (The sun was setting, and the birds were returning to their nests)

Complex sentences

• Contain one independent clause and at least one dependent clause
• Use subordinating conjunctions to connect clauses
• Express relationships between ideas (cause-effect, condition, time)
• Add depth and nuance to writing
• Can place dependent clauses at the beginning, middle, or end of sentences
• Require proper punctuation to clarify relationships between clauses (Because it was raining, we decided to stay indoors)

Compound-complex sentences

• Combine elements of compound and complex sentences
• Include at least two independent clauses and one or more dependent clauses
• Allow for expression of multiple related ideas with varying levels of importance
• Require careful punctuation and structure to maintain clarity
• Provide sophisticated sentence variety in writing
• Can be challenging for readers if overused or poorly constructed (Although the weather was terrible, we went to the beach, and we had a great time despite the rain)

Sentence functions
