Answer:
1. Coordinating conjunction- A conjunction that joins words or groups of words of equal rank.
2. Subordinating conjunction- A conjunction that introduces a clause of lower rank than the main clause.
Explanation:
Coordinating conjunctions are those types of conjunctions that are used to join two words or phrases, or nouns or other verbs or phrases and even independent clauses. They are used in the typical form of connecting sentences and words to make a new and adjoining sentence.
Whereas subordinating conjunctions are those types of conjunctions that are used to introduce a clause that is minor to a main clause. They join a dependent clause to an independent clause, or even joins adverb clauses.
While coordinating conjunctions are limited (for, and, nor, but, or, yet, so), subordinating conjunctions are more diverse and more in number. The most common ones are 'because, even though, while, unless, though' etc. Also, coordinating conjunctions are used between two sentences whereas subordinating conjunctions are mostly used even in starting a sentence, which is not the case for coordinating conjunctions.
