There was a time when the English in use in India was completely UK-English. I remember spelling "colour", "honour" and "neighbour" in school, without any confusion or fore/after-thought. Then somewhere around 15 years ago, things began to change, when my attention was elsewhere. Then- when I looked again, everywhere there were "color", "honor" and "neighbor", spellings changed, pronunciations changed. No, not everywhere. Newspapers stayed loyal to the older version - they do, to this day. However, hoardings, displays and other miscellaneous territories were taken over by this new(US) version of English.
The problem with smooth transition to the new English was that no one realised that such a transition has happened. People thought they had been spelling words and articulating all wrong, all this time. It is a foreign language, anyway. One never knows.
When I started writing - like, serious writing - I did not pay much attention to "what English" I was using. What English, as in UK English, US English, Canadian, Australian, etc. ('Indian' English being mostly identified by the mixed-up grammar due to direct translation from the Mother-tongue and pronunciations, and rarely by the spellings.) The result was a splash of color, honour, neighbors, recognise, realize and so on. Looking back now, I guess I failed to even notice the red underline that the very helpful MS Word and other word editors provided.
Then one day I decided that I shall be following the Mother of all English, the Queen's English, otherwise known as UK English, from now on. Once this decision was reached, it was essential to know the differences between the most common two versions found in this region - UK and US.
The last three years have been an eye-opener for me in terms of my acquaintance with the language. Once I decided that I will follow UK English (primarily, - for I cannot keep away the expressions that diffuse from different parts of the world, the 'American', 'British' and 'Indian' versions, and I can hardly identify them for where they belong!), it was imperative that I know what the differences between the two were. So, my saviour Google came to my aid. (I list a few of them here, the remaining can be found in the sites I have mentioned below.)
* British English words that end in -re (e.g. centre, fibre, theatre) often end in -er in American English (center, fiber, theater).
* British English words that end in -our (e.g. colour, humour) usually end with -or in American English (color, humor).
* Verbs in British English that can be spelled with either -ize or -ise at the end (e.g. recognize/recognise) are always spelled with -ize in American English.
* Verbs in British English that end in -yse (e.g. analyse) are always spelled -yze in American English (analyze).
* In British spelling, verbs ending in a vowel plus l double the l when adding endings that begin with a vowel (e.g. travel, travelled, traveller). In American English the l is not doubled (travel, traveled, traveler).
* British English words that are spelled with the double vowels ae or oe (e.g. archaeology, manoeuvre) are just spelled with an e in American English (archeology, maneuver).
* Some nouns that end with -ence in British English (e.g. licence, defence) are spelled -ense in American English (license, defense).
* Some nouns that end with -ogue in British English (e.g. dialogue) end with -og in American English (dialog).

I do not know the Canadian or Australian versions of the language, are they similar to US or UK, or much different?
Welcome any thoughts on this!
