There are many many abbreviations used for words on CW, ranging from commonly used abbreviations like B4 for Before or TU for Thank You to very obscure abbreviations known only to the one using them. Thus such a list must be a very subjective list. The following are what I believe to be the most common and easiest to understand abbreviations.
