British and American spelling

There are several words in British and American English that have same meaning but different spelling in our day to day English language usage. The need to study and get acquainted with those words and spelling is imperative for better understanding of each of the word so that we won't get ourselves confused towards using them in our sentences. The differences often come about because British English has tended to keep the spelling of words it has absorbed from other languages (e.g. French, latin greek etc), while American English has adapted the spelling to reflect the way that the words actually sound when they are spoken.

It is Imperative to stick to one spelling, be it British or American. In some cases, American spellings are acceptable in British English, especially some words ending with -ize/-ization. While you can use both the -ise/-isation or the -ize/ization endings in British English, it's important to stick to one style or the other throughout the same piece of writing.

Below are the main ways in which British and American spelling are different.
