Okay, 1337 is a good subject to talk about. The first thing I would like to clear up is that chatspeak and 1337 are NOT the same thing. Some lazy morons merge 1337 and chatspeak together, soon creating the popular belief that 1337 and chatspeak are the same thing.

Okay, so what /is/ 1337 in the first place? 1337 means Elite. The point of 1337 is to replace all the letters with symbols, and is quite fun to play with. 1337 was first created by some people would wanted to talk in a forum without any outsiders barging in. Some outsiders may have figured out the language and started using it as well. Eventually, 1337 became famous all over the internet. The original use of 1337 is hardly practiced any more, but it survives because many of peope use it for fun.

Doesn't 1337 speak come from Counter-Strike 1.6?

From there we started using nub and n00b, and h4x and the language evolved...

7h475 6234t / th4t5 6r34t / thats great -- or n!nj4 / |\|1|\|j4 / n1nj4 -- you get it..

1337 Speak has its roots much earlier than days of the internet. Telegraph operators used many of the common 1337 words seen today when sending messages in morse code. It made messages much shorter and faster to send via telegrapy. Some common words used by telegraphers that crept into 1337 speak: you: u; are: r; are you: ru; yours: urs; See you again; cuagn; before b4; See you later: cul; good morning: gm; good evening: ge; back to you: btu; weather: wx; old man: om; young lady: yl; wife: xyl; hear: hr; good: gud; pause: bt; from: fm; today: 2day; and: es; Farenheit: f; temperature: temp; degrees: deg
Typical morse code transmission by a ham radio operator using what is now condidered 1337 speak:
hi om bt gud to hr fm u 2day bt wx hr warm es sunny bt temp hr 46 deg f bt so btu john

The menial and unflattering, although sometimes fun, language of numbers and letters that began on internet games and forums, and has now somehow made its way into real life. "1337" is pronounced "leet", short for "elite."
