When I learned about the parts of speech in school, my teacher included expletives in her list.
Maybe this teacher just liked matched columns in the list.
Expletives are expressions of surprise or similar strong emotion, and they generally appear all by themselves and are generally punctuated with an exclamation point. I leave it as an exercise for the reader to make a list of them…
Two things I have opinions about! Panel 1 and panel 2.
The phrase in panel 1 is correct. Do you see it? Many many people get it wrong. Answer below
Panel 2 is grammatical but not true! Lots of people use this phrase incorrectly, too. What is it?
Panel one: “all right” two words is correct. Many folks incorrectly use “alright.” ick.
Panel 2: Use “can’t wait” only if you describe doing something because you can’t actually wait. If all you want to do is emphasize your desire for something to happen, say “I can hardly wait.” harrumpf.
