Sentence analysis might sound complicated, but when you understand how to build sentences, you can communicate more clearly and spot mistakes easily.
In this blog, we’ll break down four main types of sentences: simple, compound, complex, and compound-complex. We’ll look at how to identify and analyze each one with simple examples.
The word “analysis” comes from Greek, and it means “to break something down into parts“
In grammar, we use analysis to break down a sentence into its different parts or elements to understand how it works. When we “analyze” a sentence, we look at how each part fits together.
This helps us see how the subject (who or what the sentence is about) and the predicate (what is happening) fit together. The main parts of a sentence are:
1. Simple Subject: The main thing or person in the sentence.
2. Simple Predicate: The action or verb in the sentence.
3. Modifiers: Words that describe or change the meaning of the subject or predicate.
4. Complements: These complete the meaning of the sentence, including:
Direct Object: Who’s on the receiving end of the action?
Predicate Objective: Nouns or pronouns that follow the verb.
Predicate Adjective: Describes the subject.
Predicate Nominative: A noun or pronoun that renames the subject.
5. Independent Elements: Parts of a sentence that standalone, like:
Interjections: Words that show emotion (e.g., “Wow!”).
Vocative: The name of someone being directly addressed.
Exclamatory Nominative: An expression of surprise or emotion.
Parenthetical Expressions: Extra information added in parentheses.
Analyzing Different Sentence Types?
Let’s explore different sentence types and their analysis.
Analyzing Simple Sentences
When analyzing a simple sentence, we first break it down into two main parts: the complete subject and the complete predicate.
Then, we look at the simple subject (the main noun) and any words that describe it (called modifiers), and we do the same for the simple predicate (the main verb) and its modifiers (and complement, if there is one).
If either the subject or the predicate is compound (meaning it has more than one part), we point out the simple subjects or predicates that are joined.
Breaking it Down
♦ Example: The polar bear lives in the Arctic regions.
Complete subject: The polar bear
Complete predicate: lives in the Arctic regions
Simple subject: bear (the noun)
Simple predicate: lives (the verb)
Modifiers:
Bear is modified by the adjectives “the” and “polar.”
Lives is modified by the phrase “in the Arctic regions.”
This phrase has:
Preposition: in
Object of the preposition: regions (noun)
Modifiers for regions: “the” (article) and “Arctic” (adjective).
♦ Example: The polar bear and the walrus live and thrive in the Arctic regions.
Complete subject: The polar bear and the walrus
Complete predicate: live and thrive in the Arctic regions
Simple subjects: Bear and walrus (joined by “and”)
These make up a compound subject.
Simple predicates: Live and thrive (joined by “and”)
These make up a compound predicate.
Modifiers:
Both “live” and “thrive” are modified by the phrase “in the Arctic regions,” just like in the first example.

Analyzing Compound Sentences
When analyzing a compound sentence, we first break it into its coordinate clauses (the two parts of the sentence that are joined together). Then, we analyze each part separately.
♦ Example: The polar bear lives in the Arctic regions, but it sometimes reaches warmer climates.
This is a compound sentence made up of two coordinate clauses, joined by the conjunction “but.”
Clause 1: The polar bear lives in the Arctic regions
Clause 2: It sometimes reaches warmer climates.
Breaking it Down
In the first clause, the complete subject is “the polar bear” and the complete predicate is “lives in the Arctic regions.”
In the second clause, the subject is “it” and the complete predicate is “sometimes reaches warmer climates.“
Simple Predicate: The simple predicate (main verb) in the second clause is “reaches,” which is modified by the adverb “sometimes.”
Direct Object: The word “climates” is the direct object, meaning it’s what the verb “reaches” is acting on.
“Climates” is further modified by the adjective “warmer” (describing what kind of climate).
Analyzing Complex Sentences
When analyzing a complex sentence, we first divide it into two parts: the main clause (the main idea of the sentence) and the subordinate clause (a part that adds extra information but can’t stand alone as a sentence).
Breaking it Down
Example #1
♦ The polar bear, which lives in the Arctic regions, sometimes reaches warmer regions.
Main clause: The polar bear sometimes reaches warmer climates.
Subordinate clause: which lives in the Arctic regions.
The complete subject of the sentence is “the polar bear, which lives in the Arctic regions.“.
The complete predicate is “sometimes reaches warmer climates.”
The simple subject is “bear“, which is modified by the adjectives “the” and “polar“. It’s also modified by the subordinate clause “which lives in the Arctic regions“.
The simple predicate is “reaches“, which is modified by the adverb “sometimes” and completed by the direct object “climates“. The word “climates” is modified by the adjective “warmer“.
The relative pronoun “which” introduces the subordinate clause.
Example #2
♦ The polar bear reaches warmer climates when the ice drifts southward.
Main clause: The polar bear reaches warmer climates
Subordinate clause: when the ice drifts southward
The complete subject is the polar bear.
The complete predicate is “reaches warmer climates when the ice drifts southward.”
The simple subject is “bear“, which is modified by the adjectives “the” and “polar“.
The simple predicate is “reaches“, which is modified by the adverbial clause “when the ice drifts southward” and completed by the direct object “climates“.
The word “climates” is modified by the adjective “warmer“.
The relative adverb “when” introduces the subordinate clause.
Example #3
♦ Example: The polar bear, which lives in the Arctic regions when it is at home, sometimes reaches warmer climates.
Main clause: The polar bear sometimes reaches warmer climates
Subordinate clause: “which lives in the Arctic regions when it is at home” (which is itself complex because it contains the adverbial clause “when it is at home” that modifies the verb “lives”)
This sentence shows how a subordinate clause can have another subordinate clause nested inside it.
Example #4
♦ Example: He says that the polar bear lives in the Arctic regions.
Main clause: He says
Subordinate clause: that the polar bear lives in the Arctic regions
The subject of the sentence is “he“, and the complete predicate is “says that the polar bear lives in the Arctic regions.”
The simple predicate is “says“, and it is completed by the direct object: a noun clause: that the polar bear lives in the Arctic regions“, introduced by the conjunction “that“.
Example #5
♦ Example: That the polar bear sometimes reaches warmer climates is a familiar fact.
Main clause: is a familiar fact
Subordinate clause: that the polar bear sometimes reaches warmer climates (This is a noun clause acting as the subject of the sentence.)
The simple predicate is “is“, and it is completed by the predicate nominative “fact”, which is modified by the adjectives “a” and “familiar“.
The conjunction “that” and serves as the subject of the sentence introduced by the subordinate clause.
This version is simplified for better understanding, breaking down the key points of complex sentence analysis in a straightforward way.

Compound-Complex Sentences
When analyzing a compound-complex sentence, we first break it down into its independent clauses (which are either simple or complex). After that, we analyze each of these clauses as if they were separate sentences.
Since a compound-complex sentence is a combination of a compound sentence and a complex sentence. It has at least two independent clauses and at least one dependent clause.

Key Takeaways
1. Break It Down: Start by breaking the sentence into its basic parts: subject, predicate, and any modifiers.
2. Analyze the Sentence Type: Determine if the sentence is simple, compound, complex, or compound-complex. This shows the sentence’s structure and idea flow.
3. Identify the Subject: The subject of a sentence tells you what the sentence is about. It could be a person, place, thing, or idea.
4. Find the Verb (Predicate): Identifying the verb (action or state of being) helps you understand what the subject is doing or what is happening to it.
5. Check for Compound Subjects or Predicates: If a sentence has more than one subject or predicate joined by conjunctions like “and,” “or,” or “but,” it’s a compound sentence.
6. Check for Sentence Fragments: Make sure the sentence expresses a complete thought. If it’s missing a subject or a verb, it’s a sentence fragment which needs to be fixed.
7. Look for Parallel Structure: Double-check if the sentence has parallel structure. This makes sentences clearer and more balanced.
8. Use Conjunctions to Identify Relationships: Conjunctions (like “and,” “but,” “although,” “because,” etc.) connect ideas within the sentence which helps you understand the relationship between the clauses.
9. Examine Punctuation: Punctuation marks like commas, semicolons, and periods help separate clauses and ideas. Analyzing punctuation helps you understand how the writer intended the ideas to flow.
10. Consider Sentence Flow: Pay attention to how sentences connect with one another. Are the ideas flowing logically? Analyzing the flow of sentences can improve coherence and make your writing more readable.
Last Words on Analyzing Sentences
Analyzing sentences is an important skill that helps us understand how writing works. Understanding sentence structure makes it easier to communicate clearly, fix mistakes, and improve your writing style.
Try analyzing sentences from your favorite books, news articles, or even your own writing. Break them down to see how the parts fit together.
Happy writing!
