Apostrophe in english grammar is used for contractions where noun or pronoun or verb combine. The apostrophe mark (‘) essentially is a spelling device used to indicate the possessive case of nouns.
As a mark of punctuation, it is used to denote the omission of one or more letters or figures. For example:
- the Spirit of ’76
- the class if ’63
Do not use the apostrophe in words that are accepted shortened forms. For example:
with s to indicate that a thing or person belongs to somebody. For example:
- My friend’s brother
- Kind Jame’s crown/ Kind Jame’s crown
- The student’s books
- The waitress’s apron
- The women’s coats
In short forms, to indicate that the letters or figures have been omitted. For example:
- I’m ( I am)
- They’d (they had/they would)
- The summer of’89 (1989)
Sometimes, with s to form the plural of a letter, a figure or an abbreviation. For example:
- During the 1990’s
- Add four 3’s and the result is 12
If figure is written in words, only ‘s’ is added.
For example: Sachin hit three fours and two sixes.
