How Do You Abbreviate Words in Text Messages?

In most cases, simply use the first letter of each word in the phrase to create an acronym. Many popular phrases, such as "let me know" or "just so you know" can easily be shortened to "LMK" or "JSYK," respectively.

Other common phrases you can shorten in text messages include "as far as I know" (AFAIK), "for what it's worth" (FWIW) and "please text back" (PTB). These common slang terms and abbreviations, also known as text speak, began due to limitations on text message length and continue today thanks to websites such as Twitter that still maintain limits of 140 characters or less.
