Interjections
An interjection is a word (or, occasionally, a phrase) to express emotion. Ouch! That hurt! Wow! He won a million dollars. Yuck! That stuff stinks. Interjections are grammatically unrelated to the rest of the sentence. That is, they don’t describe any other word (like adjectives describe nouns) & don’t go together with anything (like subject + verb). They’re normally separated from the sentence by an exclamation point (!) or a comma.
There’s really not much else to say about interjections, so let’s see if you can identify them. Exercise page http://www.phschool.com/atschool/writing_grammar_08/grade11/exercise_bank/chapter17/wag11_act_17-4c.cfm http://www.quia.com/cb/56972.html
