I realize that there are more important things in the world to worry about than the misuse of the apostrophe, but still, it is aggravating. Why can’t people – highly intelligent people at that – use the apostrophe appropriately? Here are some helpful hints:
NO apostrophe is needed when the word is plural:
The boys in the band are crazy.
When showing possession for ONE boy, the apostrophe is before the “s”:
The boy’s band is crazy. (By himself… Before)
When showing possession for many boys, the apostrophe is after the “s”:
The boys’ band is crazy. (Think of All the boys… After)
