An interjection is a word or phrase that expresses feeling rather than meaning. Interjections are grammatically independent from the words around them and are often used to express sudden bursts of emotion. 

Here are some examples of interjections:
"Oh, what a beautiful house!"
"Uh-oh, this looks bad"
"Alas"
"Ouch!"
"Oh my!"
"Wow!"
"Yikes!"
"Yahoo!"
"Oops"
"Terrific!"  

Interjections are a part of speech, but they are not grammatically connected to other parts of a sentence. They are considered parenthetical and are set off with commas. 
Interjections are common in everyday speech and informal writing. However, they should be avoided in formal writing because they may make it seem like the topic is not being taken seriously.
