1. What is a sentence?
A sentence is a group of words that express a complete thought. It usually has a subject (who or what the sentence is about) and a predicate (what is said about the subject) and expresses a statement, question, command, or exclamation. In English, a sentence starts with a capital letter and ends with a punctuation like a period, question mark, or exclamation mark. Understanding the structure of a sentence is important because it helps you express your ideas clearly.
2. Basic sentence structures in English
Two-word sentence structures
At its most basic level, a sentence in English is comprised of two elements: a subject and a verb, which together convey a complete idea. The subject indicates the person or thing performing the action and is always a noun or pronoun. The verb demonstrates the action taken or the state of being. This can either be an action verb, such as jump, or a state verb like appear.
- She left.
- Fire burns.
- Water evaporates.
- Humans age.
To make sentences more informative, we can add an object. In the next section, we will look into the SVO pattern in English.
The Subject + Verb + Object (SVO) pattern in English sentences
The SVO pattern is a common structure in English sentences. In the SVO structure, the sentences start with the subject (the person or thing doing the action), followed by the verb (the action itself), and finally the object (the person or thing receiving the action).
- Subject (S): The subject is the person or thing that does the action in a sentence.
- Verb (V): The verb is the action that the subject is doing.
- Object (O): The object is the person or thing that is affected by the action of the verb.
- She left yesterday.
- She eats breakfast.
- I love chocolate.
- He is writing a letter.
- Humans age over time.
Adding adjectives in sentences
To make our sentence more descriptive, we can add an adjective. An adjective is a word that describes or modifies a noun.
- The curious dog sniffed the toy.
- The dog sniffed the new toy.
- The curious dog sniffed the new toy.
3. Advanced sentence structures
3. 1. Compound-complex sentences
Compound-complex sentences combine at least two independent clauses and one or more dependent clauses. This structure is useful for conveying detailed information and multiple actions or ideas.
- While I was studying, my friend called to invite me to a movie, but I had to decline because I had an exam the next day.
- She loves playing the guitar, and although she hasn't had any formal training, she’s become quite skilled.
- Although she was tired, she finished her homework, and she went to bed.
- When the storm ended, we went outside, and we saw the damage it had caused.
- The teacher returned the tests because she finished grading them, but she still had comments to add.
- Since it was raining, we decided to stay inside, but we still enjoyed our time together.
- He was excited about the trip, yet he felt nervous because he had never traveled alone before.
- As soon as the sun rose, they started hiking, and they planned to reach the summit by noon.
- If she arrives early, she can join us for dinner, or she can wait until we finish eating.
- The car broke down on the way, so they called for help, but no one answered immediately.
- Although he tried his best, he couldn’t solve the puzzle, so he asked his friend for help.
- Whenever they have free time, they enjoy hiking, and they often explore new trails together.
3.2 Parallel structures
Parallel structure, or parallelism, uses repeated grammatical patterns within a sentence for rhythm and clarity. It’s common in lists, comparisons, and expressions of contrasting ideas. Parallel structures can be joined by using coordinating conjunctions (for, and, nor, but, or, yet, or so).
- He enjoys hiking, biking, and swimming.
- The task was neither easy nor quick.
- She likes reading books, writing stories, and painting pictures.
- He enjoys playing football, swimming in the pool, and hiking in the mountains.
- Our team needs to practice more, work together, and communicate better.
- She wants to go to the beach, build sandcastles, and explore the city.
- The company offers flexible working hours, competitive salaries, and health benefits.
- He is good at singing, dancing, and playing the guitar.
- They are planning to visit Paris, explore the Louvre, and enjoy French cuisine.
- The movie was exciting, funny, and emotionally moving.
- He studied for the test, completed his assignments, and practiced his speeches.
- The teacher asked the students to write essays, read articles, and participate in discussions.
3.3 Inverted sentence structures
Inversion places the verb or complement before the subject for emphasis or stylistic effect. It’s often seen in formal writing, poetry, and for dramatic emphasis.
- Seldom have I seen such dedication.
- Into the forest wandered the children.
- Never have I seen such a beautiful sunset.
- Hardly had she finished her homework when the phone rang.
- Only after the meeting did I understand the full details of the project.
- At no time should you ignore the safety instructions.
- Seldom have we experienced such a warm winter in this area.
- Not only did they win the game, but they also set a new record.
- Rarely do we get the chance to travel abroad.
- Not until the last moment did they decide to leave the event.
- So shocked was he that he couldn’t speak for a moment.
3.4 Emphatic sentence structures
Emphasis in English can be added with the use of auxiliary verbs like do/does in affirmative sentences or the cleft structure, which uses "it is/was" or "what".
- She does understand the issue.
- It was her performance that impressed the judges.
- I do like this new book!
- She does enjoy playing the piano every day.
- We did see the movie last night!
- They do work hard to achieve their goals.

- You do look amazing in that dress!
- I really do believe in your potential!
- She does speak five languages fluently.
- They did arrive on time for the meeting!
- He does know how to play the guitar very well.
3.5 Cleft sentences
Cleft sentences split information into two parts, often starting with It is/was or What. This structure adds focus to a specific part of the sentence.
- It was at midnight that the alarm went off.
- What she needed was love.

- What I need right now is a cup of tea.
- The reason she left early was because she had a meeting.

- It was in New York where they met for the first time.
- The thing that surprised me most was his reaction.

3.6 Relative clauses with advanced constructions
Relative clauses add information about nouns. Advanced relative constructions often use non-essential (non-restrictive) clauses, beginning with which, whose, where, and when.
- The project, which took months to complete, was finally a success.

- The book, which she finished in one night, became her favorite.

3.7 Concessive clauses
Concessive clauses express a contrast and often start with although, though, or even though.

3.8 Absolute phrases
Absolute phrases provide additional information about the sentence without directly modifying it and often include a noun and a participle. They follow one of the following structures:
- [Noun] + [Participle]: Weather permitting, we will go hiking tomorrow.
- [Noun] + [Participle] + [Modifiers]: His confidence restored, he began his presentation.
- [Noun] + [Participle] + [Object]: Her eyes shining with excitement, she opened her gift.

3.9 Nominalisation
Nominalisation turns verbs or adjectives into nouns, creating more formal or academic sentence structures. In the following exemples, we use nominalisations like discovery, explanation, implementation, etc. to present actions or descriptions as nouns, shifting the focus from the actions themselves to the results or concepts.

3.10 Conditional sentences
Conditional sentences express a condition and its possible result. They usually consist of two clauses: a conditional (or "if") clause that presents the condition, and a main clause that describes the result or outcome if the condition is met. Conditional sentences are used to talk about possible, hypothetical, or even unreal situations, often involving possibilities, probabilities, or hypothetical scenarios.
