We bought Emi the special edition Schoolhouse Rock video a couple of years ago when she was 3 and she thought it was lame. Now that she's a big Kindergartner, she's all into it. I asked her which vid was her fave and of course she said "Interjections!!"
Interjections (Hey!) show excitement (Hey!) or emotion (Hey!).
They're generally set apart from a sentence by an exclamation point,
Or by a comma when the feeling's not as strong.
Interjections show excitement or emotion,
Hallelujah, Hallelujah, Hallelujah... YEA!
Darn! That's the end!
