Grammar - Apostrophes

By Stuart Ackerman

Apostrophes are those little commas that dangle in the air (').  Apostrophes show changes in the function of words.
 
 
1.  Use an apostrophe to create a possessive of a singular or plural noun.
 
For example,
 
David's hockey skills.  (the skills belong to David)
 
The girls' outfits were pretty.  (the outfits belonging to more than one girl)
 
 
2.  Use apostrophes to create contractions.
 
For example,
 
they + are = they're
who + is = who's
it + is = it's
