Subordinate and Coordinate clauses
This part of grammar was always my most hated...and for anyone who struggles with them, I hope this helps.
A (very) simple and not quite correct definition of a clause would be: a syntactic object longer than a phrase.
The difficulty with clauses is 1) Identifying a clause 2) Identifying the type of clause.
For this post, I will be focusing on the subordinate and the coordinate clauses.
A clause is subordinate when it is linked by a subordinating conjunction or a relative pronoun (who, which, etc)
There are two main types of suborinating conjections:
1) Simple (one word subordinators) - although, if, while, since, that...
2) Complex (multi word subordinators) - as long as, such that...
There is also a third, called correlative which are a rarer example of paired subordinators such as 'the less I do, the more I like it'
Subordinate clauses do not form a grammatically correct sentence when isolated from the rest of the sentence.
Subordinate clauses also must contain a subject and a verb.
'I cannot go to college until I am fully awake' - 'until' is the subordinating conjunction.
'I live by the sea because I like the sand' - 'because' is the subordinating conjunction.
The coordinate clause is linked by a coordinating conjunction, and there are seven: for, and, nor, but, or, yet, so.
Coordinate clauses make grammatical sense alone.
'I like ice cream but I hate chocolate'
A lot more similar to its subordinating sibling!
