Punctuation is the basic element of English grammar and without it a sentence is not only incomplete but also insensible. There are various marks of punctuation that are used in sentences to give them more meaning and make it easier for the reader to understand. If we omit these punctuation marks from a sentence we will be left hanging. Also, without a punctuation mark a sentence can have various meanings and the reader might assume the meaning the writer is not conveying.
Point of Exclamation:
The exclamation point is used in English sentences when the feelings or emotions are expressed. The expression of any kind of emotion like happy, frustrated, angry or excited etc. are all accompanied by an exclamation mark.
Yay! We won the match.
In the above example, the word ‘yay’ at the beginning indicates excitement and tells the reader that the person saying the above sentence is very excited about winning the match. Thus exclamation mark is used after ‘yay’.
Get out of my house!
Exclamation mark can also be used for a strong emotion at the end of a sentence.
Stop messing around my work!
