Complex Sentence

A complex sentence has one or more dependent clauses (also called subordinate clauses). Since a dependent clause cannot stand on its own as a sentence, complex sentences must also have at least one independent clause. In short, a sentence with one or more dependent clauses and at least one independent clause is a complex sentence.

A sentence with two or more independent clauses plus one or more dependent clauses is called compound-complex or complex-compound.

In addition to a subject and a verb, dependent clauses contain a subordinating conjunction or similar word. There are a large number of subordinating conjunctions in English. Some of these give the clause an adverbial function, specifying time, place, or manner. Such clauses are called adverbial clauses.

When I stepped out into the bright sunlight, from the darkness of the movie house, I had only two things on my mind. (S. E. Hinton, The Outsiders))
This complex sentence contains an adverbial clause, When I stepped out into the bright sunlight from the darkness of the movie house. The adverbial clause describes when the action of the main clause, I had only two things on my mind, took place. A relative clause is a dependent clause that modifies a noun or noun phrase in the independent clause. In other words, the relative clause functions similar to an adjective.

• Let him who has been deceived complain. (Miguel de Cervantes, Don Quixote)
• You, who have never known your family, see them standing around you. (J.K. Rowling, Harry Potter and the Sorcerer's Stone)

A noun clause is a dependent clause that functions like a noun.

In the first example, the restrictive relative clause who has been deceived specifies or defines the meaning of him in the independent clause, Let him complain.

In the second example, the non-restrictive relative clause who have never known your family describes you in the independent clause, You see them standing around you.

A noun clause may function as the subject of a clause, or as a predicate nominative or an object.
What she had realised was that love was that moment when your heart was about to burst. (Stieg Larsson, The Girl with the Dragon Tattoo)
In this sentence the independent clause contains two noun clauses.
The noun clause What she had realized serves as the subject of the verb was, and that love was that moment serves as complement. The sentence also contains a relative clause, when your heart was about to burst.

Independent clause

An independent clause (or main clause) is a clause that can stand by itself as a simple sentence. An independent clause contains a subject and a predicate and makes sense with another word(s).

Independent clauses can be joined by using a semicolon or by using a comma followed by a coordinating conjunction (and, but, for, or, nor, so, yet)

Examples

In the following example sentence, independent clauses are in italic, and conjunctions are in bold. Single independent clauses:

• I have enough money to buy an ice cream cone.
• My favourite flavour is chocolate.

Multiple independent clauses:

• I have enough money to buy an ice cream cone**;** my favourite flavour is chocolate.
• I have enough money to buy an ice cream cone, so let's go to the shop.

Dependent Clause

A dependent clause is a clause that provides a sentence element with additional information, but which cannot stand alone as a sentence. A dependent clause can either modify an adjacent clause or serve as a component of an independent clause. Some grammarians use the term subordinate clause to refer only to adverbial dependent clauses.

The different types of dependent clauses include content clauses (noun clauses), relative (adjectival) clauses, and adverbial clauses.

In Indo-European languages, a dependent clause usually begins with a dependent word. One kind of dependent word is a subordinating conjunction. Subordinating conjunctions are used to begin dependent clauses known as adverbial clauses, which serve as adverbs.

In the following examples, the adverbial clauses are bold and the subordinating conjunctions are italicized:

• Wherever she goes, she leaves her luggage (The adverbial clause wherever she goes modifies the verb leaves.)
• Bob enjoyed the movie more than I did. (The adverbial clause than I did modifies the adverb more.)

A subordinating conjunction can also introduce a noun clause:

• I know that he likes me. (The noun clause that he likes me serves as the object of the main-clause verb know.)

Another type of dependent word is the relative pronoun. Relative pronouns begin dependent clauses known as relative clauses; these are adjective clauses, because they modify nouns. In the following example, the relative clause is bold and the relative pronoun is italicized:

• The only one of the seven dwarfs who does not have a beard is Dopey. (The adjective clause who does not have a beard describes the pronoun one.)

A relative adverb plays the part of an adverb in a relative clause, as in

• That is the reason why I came. (The relative clause why I came describes the noun reason, and within the relative clause the adverb why modifies the verb came.)
• That is the place where he lives. (The relative clause where he lives describes the noun place, and within the relative clause the adverb where modifies the verb lives.)

An interrogative word can serve as an adverb in a noun clause, as in

• No one understands why you need experience. (The noun clause why you need experience functions as the direct object of the main-clause verb "understands", and within the noun clause why serves as an adverb modifying need.)

A2 | Elementary | Pre-intermediate

CEFR A2 is the second level in the Common European Framework of Reference for Languages, often called elementary or pre-intermediate. If you're at this stage, you've moved beyond the basics of A1 and can handle simple, real-life communication — but you're still building the foundations you'll need for B1 and beyond.

What can an A2 learner do?

At A2, you can:

• Understand everyday expressions related to familiar topics — personal details, family, shopping, work, and your local area.
• Communicate in routine situations that involve a simple, direct exchange of information (e.g. ordering food, asking for directions, making small talk).
• Describe your background and immediate environment in simple terms — where you live, what you do, what you need.
• Read and understand short, simple texts like signs, menus, timetables, and brief personal messages.

Key grammar at A2

At this level, you're expected to be comfortable with several core grammar areas:

• Past simple and past continuous — talking about completed actions and actions in progress in the past.
• Present perfect — connecting past events to the present (I've visited London twice).
• Basic modal verbs — expressing ability, permission, necessity, and possibility (can, must, should, have to).
• Common question forms — both simple and slightly more complex (How long have you lived here?).
• Articles and determiners — using a/an/the correctly, along with words like some, any, few, little.
• Basic conditionals — first conditional and simple uses of if and wish.

You're also expanding your vocabulary through collocations (natural word pairings like make a decision or take a break) and learning to use gerunds and infinitives with common verbs.

How A2 differs from A1 and B1

Compared to A1, A2 learners can do more than just produce isolated phrases — you can link simple sentences and participate in short conversations. Compared to B1, you're still relying on familiar contexts and predictable language; handling unexpected topics or expressing opinions in detail comes at the next level.

Self-check: If you can describe your daily routine, talk about past experiences, and handle a basic conversation at a shop or restaurant — but struggle when the topic gets abstract or unfamiliar — you're likely at A2.
