Definition
Noun: A subordinating conjunction is a type of conjunction that connects a dependent (subordinate) clause to an independent (main) clause. It introduces the dependent clause and shows the relationship between the two clauses, such as cause, time, condition, or contrast. The subordinating conjunction makes the clause it introduces grammatically dependent on the main clause.
Usage
A subordinating conjunction is used at the beginning of a dependent clause to link it to an independent clause, forming a complex sentence. The dependent clause cannot stand alone as a complete sentence.
Examples
- (The subordinating conjunction "after" introduces the dependent clause "you arrive," showing a time relationship.)
- (The subordinating conjunction "because" introduces the dependent clause "she was ill," showing a cause-and-effect relationship.)
- (The subordinating conjunction "if" introduces the dependent clause "he will come," showing a condition.)
- (The subordinating conjunction "although" introduces the dependent clause "he studied hard," showing a contrast.)
Advanced Usage
- Elliptical Clauses: Sometimes, parts of the dependent clause can be omitted after the subordinating conjunction if they are understood from context.
- While [he was] reading, he fell asleep.
- Initial Position: When a sentence begins with a dependent clause introduced by a subordinating conjunction, a comma is usually placed after that clause.
- Since it's raining, the picnic is canceled.
