Abbreviations are shortened forms of words, phrases or sounds. They are commonly used when chatting on Facebook to reduce the amount of typing needed to get a thought across. The problem is, not everyone knows what all the abbreviations stand for, and this can result in confusion and frustration. If you are one of these people, focus on learning the most common abbreviations first.
The first group of abbreviations includes those formed by combining the first letter of each word in a phrase. You can usually tell that an abbreviation falls into this category because each letter in the abbreviated word will be a capital. Some common examples include BTW, meaning "by the way;" IDK, meaning "I don’t know;" IMHO, meaning "in my humble opinion;" LOL, meaning "laugh out loud;" and TTYL, meaning "talk to you later."
The second group of abbreviations includes those formed by removing specific letters from a word. You can usually tell that an abbreviation falls into this category because lowercase letters are used. Some common examples include b/w, meaning "between;" fb, meaning "Facebook;" msg, meaning "message;" pls, meaning "please;" and ppl, meaning "people."
The third group of abbreviations includes those that sound like the longer word they imitate. You can usually tell that an abbreviation falls into this category because the word sounds they way it is intended to when spoken. Some common examples include B4, meaning "before;" K, meaning "okay;" L8, meaning "late;" L8r, meaning "later;" and U'll, meaning "you'll."
The final group of abbreviations is a much shorter one. It includes those meant to imitate sounds. Some common examples include mmm, meaning "yummy;" ow, meaning "ouch;" WooHoo, meaning "happy cheer;" and zzz, meaning "sleeping."
