Sentence Structure & Phrases - Study Notes
Mastering sentence structure and phrases is crucial for professional communication in government service. This comprehensive guide covers the fundamental components of English sentences, from basic elements to complex constructions, enabling you to communicate effectively in official correspondence, reports, and public documents. Understanding these concepts is essential for the Civil Service Examination's Verbal Ability section and for maintaining the high standards of written communication expected in professional government positions.
Summary
Mastery of sentence structure and phrases is fundamental to professional communication in government service. Understanding the components of sentences—subjects, predicates, objects, and complements—enables clear expression of complex ideas. The four sentence types (simple, compound, complex, compound-complex) provide varied structures for different communication needs. Phrases add sophistication and precision to writing, while proper handling of independent and dependent clauses prevents structural errors. Avoiding run-on sentences, fragments, and other common errors maintains the professional standards essential for effective government communication. These skills directly contribute to success in the Civil Service Examination and professional advancement in public service.
Sections
Every sentence in English contains two essential elements: a subject (the noun or pronoun performing the action) and a predicate (the verb and any accompanying elements that complete the thought). The subject answers 'who' or 'what' performs the action, while the predicate explains what the subject does or what happens to it. Beyond these core elements, sentences may include objects (direct and indirect), complements (subject and object), and various modifiers that enhance meaning and precision. Understanding these components allows for the construction of clear, professional communications essential in government service.

Fundamental Components of Sentence Structure
Examples
- The Secretary (subject) announced the new policy (predicate with direct object).
- The department (subject) gave employees (indirect object) additional training (direct object).
- The proposal (subject) seems comprehensive (subject complement).
- The committee (subject) declared the project (direct object) successful (object complement).
Key Points
- Subject: the performer of the action (noun, pronoun, or noun phrase)
- Predicate: contains the verb and completes the thought about the subject
- Direct object: receives the action of a transitive verb directly
- Indirect object: indicates to whom or for whom the action is performed
- Subject complement: follows linking verbs and describes or identifies the subject
- Object complement: describes or identifies the direct object
Sentences are classified into four structural types based on the number and types of clauses they contain. Simple sentences contain one independent clause with a complete thought. Compound sentences combine two or more independent clauses using coordinating conjunctions (FANBOYS: for, and, nor, but, or, yet, so) or semicolons. Complex sentences feature one independent clause and at least one dependent clause connected by subordinating conjunctions. Compound-complex sentences contain multiple independent clauses and at least one dependent clause. Professional writing benefits from varying sentence structures to maintain reader engagement and demonstrate sophisticated communication skills.

Types of Sentences by Structure
Examples
- Simple: The Civil Service Commission implements merit-based recruitment.
- Compound: The policy was approved, but implementation requires additional funding.
- Complex: Although the budget was tight, the department completed all projects on schedule.
- Compound-complex: The new system was installed last month, and while it requires training, employees have adapted quickly.
Key Points
- Simple sentence: One independent clause with complete thought
- Compound sentence: Two or more independent clauses joined by coordinating conjunctions
- Complex sentence: One independent clause + one or more dependent clauses
- Compound-complex sentence: Multiple independent clauses + at least one dependent clause
- Coordinating conjunctions: FANBOYS (for, and, nor, but, or, yet, so)
- Subordinating conjunctions: because, although, when, if, since, while, etc.
Phrases are groups of related words that function as single units within sentences but lack the subject-predicate combination necessary to form complete clauses. Each type of phrase serves specific grammatical functions and adds depth to sentence construction. Noun phrases function as subjects, objects, or complements; verb phrases indicate action or state of being; adjective phrases modify nouns or pronouns; adverb phrases modify verbs, adjectives, or other adverbs; prepositional phrases show relationships between elements; and participial, gerund, and infinitive phrases add sophisticated variety to sentence construction. Effective use of phrases enhances the precision and professionalism of government communications.

Understanding Phrases and Their Functions
Examples
- Noun phrase: 'The comprehensive budget proposal' serves as the subject.
- Verb phrase: 'has been carefully reviewed' shows completed action.
- Adjective phrase: 'extremely beneficial to public welfare' modifies the noun 'program'.
- Adverb phrase: 'with great efficiency' modifies how the work was completed.
- Prepositional phrase: 'According to the latest statistics' introduces supporting evidence.
- Participial phrase: 'Having completed the audit' provides background information.
- Gerund phrase: 'Implementing new policies' requires careful planning.
- Infinitive phrase: 'To serve the Filipino people' expresses purpose or goal.
Key Points
- Noun phrases: function as subjects, objects, or complements
- Verb phrases: main verb plus auxiliary verbs or modifiers
- Adjective phrases: modify nouns or pronouns
- Adverb phrases: modify verbs, adjectives, or other adverbs
- Prepositional phrases: begin with prepositions and show relationships
- Participial phrases: begin with present or past participles
- Gerund phrases: -ing forms functioning as nouns
- Infinitive phrases: 'to' + base verb form with various functions
Clauses are groups of words containing both subjects and predicates. Independent clauses express complete thoughts and can stand alone as sentences, while dependent clauses contain subjects and predicates but cannot stand alone due to subordinating words that create incomplete thoughts. Dependent clauses are introduced by subordinating conjunctions (because, although, when, if, since, while, unless, until) or relative pronouns (who, whom, whose, which, that). Proper identification and punctuation of these clauses prevent common errors like run-on sentences and sentence fragments, both of which undermine professional communication standards required in government service.
Heading
Independent and Dependent Clauses
Examples
- Independent: 'The department completed its quarterly report.'
- Dependent: 'Because the deadline was approaching' (incomplete thought)
- Combined: 'Because the deadline was approaching, the department worked overtime.'
- Relative clause: 'The employee who submitted the proposal received recognition.'
- Noun clause: 'What the committee decided remains confidential.'
- Adverbial clause: 'When the meeting concluded, participants felt satisfied.'
Key Points
- Independent clause: complete thought that can stand alone
- Dependent clause: incomplete thought requiring connection to independent clause
- Subordinating conjunctions introduce dependent clauses
- Relative pronouns (who, whom, whose, which, that) introduce relative clauses
- Dependent clauses function as nouns, adjectives, or adverbs
- Proper punctuation prevents run-on sentences and fragments
- Comma usage depends on clause position and type
Professional writing requires avoiding common structural errors that compromise clarity and credibility. Run-on sentences occur when independent clauses are improperly connected with only commas (comma splices) or run together without proper punctuation. These can be corrected by separating clauses with periods, semicolons, or appropriate conjunctions. Sentence fragments occur when dependent clauses are punctuated as complete sentences or when essential sentence elements are missing. Fragment correction involves either combining fragments with complete sentences or adding missing elements. Subject-verb disagreement, misplaced modifiers, and faulty parallelism also undermine professional communication and must be identified and corrected.

Common Sentence Errors and Corrections
Examples
- Run-on error: 'The policy was approved, implementation begins next month.'
- Corrected: 'The policy was approved; implementation begins next month.'
- Fragment error: 'Because the budget was inadequate for the project.'
- Corrected: 'Because the budget was inadequate, the project was postponed.'
- Agreement error: 'The committee have decided to postpone the meeting.'
- Corrected: 'The committee has decided to postpone the meeting.'
- Parallelism error: 'The goals include reducing costs, improving efficiency, and to increase satisfaction.'
- Corrected: 'The goals include reducing costs, improving efficiency, and increasing satisfaction.'
Key Points
- Run-on sentences: Independent clauses improperly connected
- Comma splices: Independent clauses joined only by commas
- Sentence fragments: Incomplete thoughts punctuated as sentences
- Correction methods: periods, semicolons, coordinating conjunctions, subordination
- Subject-verb agreement: Subjects and verbs must match in number
- Parallel structure: Similar elements must have consistent grammatical form
- Modifier placement: Modifiers must clearly modify intended words
