Prepositions, Conjunctions, and Interjections
Prepositions, conjunctions and interjections are the connecting elements in sentences. Finding the link between words is the secret to identifying prepositions. The two most important rules about using prepositions are: avoid using excess prepositions and avoid ending sentences with prepositions.
Conjunctions are parts of speech that connect words, phrases or clauses. There are three types of conjunctions: coordinating, correlative, and subordinating. They are the key to logically constructed sentences.
Interjections are used to express powerful or sudden emotion and are usually not grammatically connected to any other sentence. While there are no formal rules for interjections, they are most effective if used sparingly.
