Interjections are one of the nine parts of speech in the English language.
An interjection is a word or phrase that expresses strong emotion or fills pauses. Interjections usually have no gramatical connection with the rest of a sentence.
Examples of an interjection include: ah, uh, er, um, oh, wow, hallelujah, cool, damn, hey, ouch, ugh, good grief.
