Simple Interjections

     "Interjection" comes from the Latin words for "throw" ("ject") and "among" ("inter"). An interjection is thus a word or construction that is "thrown among" the words in a sentence. Unlike all the other words, interjections DO NOT chunk to the rest of the sentence. Instead, they usually indicate an attitude about the entire sentence. 

In speech, short interjections are common:

Golly, Peter looks sick!
Uhm, do you think supper is ready?
Ah, it's a beautiful day!
Ouch! That hurt.
Whew, that was close.
Well, I thought I was right.
Alas, all is lost.
Gee, I forgot!
Interjections such as those above are not considered proper in formal writing, but the following, which consist of prepositional phrases, are common to both writing and speech:
In fact, Peter was lucky.
He was, in my opinion, brave.
Of course Freddie won.
"In fact" here simply emphasizes the writer's belief that the sentence is factual, whereas "in my opinion" suggests that the sentence may not be. "Of course" suggests that the statement is obviously true. (But sometimes it may not be.)
