The correct conjunction to complete the sentence is "so." This is because "so" is used to indicate a logical consequence or result. In this sentence, being tired is the reason for going to bed early.
The conjunction "but" is not correct because it is used to indicate a contrast or opposition between two ideas. "Yet" is not correct because it is used to indicate that an action or event has not happened, although it was expected or planned. The conjunction "or" is not correct because it is used to indicate a choice or alternative between two or more options.
Sentence
A simple sentence consists of only one clause.
A compound sentence consists of two or more independent clauses.
A complex sentence has at least one independent clause plus at least one dependent clause.
A set of words with no independent clause may be an incomplete sentence, also called a sentence fragment.
A sentence consisting of at least one dependent clause and at least two independent clauses may be called a complex-compound sentence or compound-complex sentence.
- I like trains.
- I don't know how to bake, so I buy my bread already made.
- I enjoyed the apple pie that you bought for me.
- The dog lived in the garden, but the cat, who was smarter, lived inside the house.
- What an idiot.
Sentence 1 is an example of a simple sentence.
Sentence 2 is compound because "so" is considereda coordinating conjunction in English, and sentence 3 is complex.
Sentence 4 is compound-complex (also known as complex-compound).
Example 5 is a sentence fragment.
The simple sentence in example 1 contains one clause.
Example 2 has two clauses (I don't know how to bake and I buy my bread already made), combined into a single sentence with the coordinating conjunction so.
In example 3, I enjoyed the apple pie is an independent clause, and that you bought for me is a dependent clause; the sentence is thus complex.
In sentence 4, The dog lived in the garden and the cat lived inside the house are both independent clauses; who was smarter is a dependent clause.
Example 5 features a noun phrase but no verb.
It is not a grammatically complete clause.
Compound Sentence
A compound sentence is composed of at least two independent clauses. It does not require a dependent clause.
The clauses are joined by a coordinating conjunction (with or without a comma), a semicolon that functions as a conjunction, a colon instead of a semicolon between two sentences when the second sentence explains or illustrates the first sentence and no coordinating conjunction is being used to connect the sentences, or a conjunctive adverb preceded by a semicolon.
A conjunction can be used to make a compound sentence. Conjunctions are words such as for, and, nor, but, or, yet, and so.
Examples:
- I started on time, but I arrived late.
- I will accept your offer or decline it; these are the two options.
- The law was passed: from April 1, all cars would have to be tested.
- The war was lost; consequently, the whole country was occupied.
The use of a comma to separate two independent clauses without the addition of an appropriate conjunction is called a comma splice and is generally considered an error (when used in the English language).
Example:
- The sun was shining, everyone appeared happy.
A2 / Elementary / Pre-intermediate
A CEFR A2 level English language user is considered to be at an elementary level. At this level, an individual is expected to have a basic understanding of the English language and be able to use simple phrases and sentences to communicate in everyday situations. They should be able to understand and use basic grammar and vocabulary, and be able to understand short, simple texts.
At A2 level, They can understand sentences and frequently used expressions related to areas of most immediate relevance (e.g. very basic personal and family information, shopping, local geography, employment). They can communicate in simple and routine tasks requiring a simple and direct exchange of information on familiar and routine matters. They can describe in simple terms aspects of their background, immediate environment and matters in areas of immediate need. They can also interact with a degree of fluency and spontaneity that makes regular interaction with native speakers quite possible without strain for either party.
