English Punctuation: Apostrophe
The apostrophe probaly causes more grief than any of the other punctuation marks put together!
The problem nearly always seems to stem from users not understandingthat the apostrophe has two very different (and very important) uses in English.
These two examples show the apostrophe being used for possession (sentence 1) and contraction (sentence 2)

- Colombia's one of the main coffee producing countries in the world.
- a ship's captain, a doctor's patient, a car's engine, Ibrahim's coat, Mirianna's book.

The POSSESSIVE APOSTROPHE
In most cases you simply need to add 's to a noun to show possession:
Plural nouns that do not end in s also follow this rule:
Ordinary (or common) nouns that end in s, both singular and plural, show possession simply by adding an ' after the s but proper nouns (names of people, cities, countries etc.) can form the possessive either by adding the 's or simply adding the ':
General notes: Many people want to know how to form the possessive of their own name when it ends in an 's' or when refering to the whole family, e.g. The Jones' children.
