A Grammar Interjection

The last months have been busy, so I fall back on my old friend, grammar.

Today, I give you interjections.

In one school of grammatical thought, interjections are a classification of English words, like nouns, verbs, pronouns, and the rest.  Interjections are words typically used in dialog or informal writing: well, eew, uh, um, yes, no, huh, aha, hey, wow, and lots of other words.  The point about interjections is they, well, interject into a sentence, usually with some emotion or emphasis.

Three interesting things about interjections.

1.  Interjections (in traditional writing) are always separated from the rest of a sentence with punctuation, usually a comma and sometimes an exclamation mark.

Well, yes!  I did know that the eggs were spoiled, but I didn't think that mother would mind eating them.

2.  The placement in the sentence does not really affect how we use interjections.  We still put commas around them.

That's the funny thing about cats, huh, you can only skin them one way, right?

3.  Like nouns and verbs and almost any other type of speech, interjections can be people, swear words, and more.

I don't want to walk through this horrible field, Randy!  Oh, hell!  It's been raining in Indiana for weeks, and, oh, drat, Mike, I have enough water in my boots to fill a bucket!

Here are a few more (remember, these can act as other parts of speech but can interject as interjections):
fantastic
whoops
careful
okay
no way
oh, dear
whoa
any swear word
onomatopoeia, too?

What else you got, huh?
