首字母縮寫是由每個單詞的第一個字母組合而成的，比如UN就是指United Nations。短信里，首字母縮寫常常被用在習(xí)慣用語中。另外，發(fā)聲相似的詞會被字母取代。
舉例：
OIC- Oh I see.
BRB - Be right back
BFN - Bye for now
LOL - Laughing out loud
ASAP - As soon as possible
BTW - By the way
FYI - For your information
JK - Just kidding
TTYL - Talk to you later
還有一種是縮略詞。短信的縮略詞不是指一些約定俗成的如"don't" 或 "they're"之類的縮略，但兩者的目的是一樣的：即當(dāng)意思很清楚的時候可將一些不需要的詞省略。元音常常會被省略，但是你仍然可以保留這個詞的大概發(fā)音。數(shù)字8有時候會發(fā)eight，所以later就寫成l8r。數(shù)字4通常也被取代成for，就像2這個音就替代了to。
舉例：
Plz - Please
Thx - Thanks
Cya - See you
L8r - Later
K - OK
U - You
R - Are
B4 - Before
2morro - Tomorrow
其它情況：
1. asl=年齡、性別、位置
2. cuz/cos=because 因為
3. 2=to 數(shù)字代替了字母
4. u/ya=you 你
5. howr u/h r u=how are you 你好嗎？你怎么樣？
6. me 2=me too 我也是
7. brb=be right back 一會兒回來
8. wb=welcome back 歡迎回來
9. sup=what'sup 這個是熟人之間問好的常用形式，就好比中國人見面問“嘛呢?"回答就直接告訴別人你正在忙什么，如果沒什么特別的可以回答not much/nothing speical。
10. uni=university 大學(xué)
11. gvmt=government 政府
12. goodnite/nite=good night晚安
13. yes/yep/yeah “好”的幾種表達
14. no/nope/nah “不”的幾種表達，個人認為總說no太單調(diào)，而且也太生硬了，可以試著其它的兩種回答
15. gotdc=got disconnected 聊到一半時，卻掉線了，這個時候應(yīng)該怎么說呢？gotdc是比較簡單的表達。
16. wanna=want to 想要...
17. gotta=got to 要...樣
18. gonna=going to 要去...
19. cya/c u=see you 再見的縮寫
20. dunno=don't know 不知道的縮寫
21. kinda=kind of 一種...
22. prob'ly=probably 很有可能...
23. lemme=let me 讓我...
24. n=and 和
25. r=are/our 是
26. gimme=give me 給我...
27. yrw=you are welcome 不客氣
28. pvt=private 私人的
29. lota=lot of 很多
30. TC=take care 保重的縮寫，聊到最后要離開，說完再見還可以說一句保重，顯得很有禮貌�；蛘撸依锏目腿艘x開，送到門口時常常會說一句保重之類的話，英文的說法就是take care。
31. favo=favorite 最喜歡的
32. 4=for 為...
33. b4=before 以前
34. jk=just kidding 開玩笑的縮寫
35. ain't=be not 不是
36. nvm=never mind 別介意
37. msg=message 信息
38. luv=love 愛
39. bro=brother 兄弟
40. sis=sister 姐妹
41. doc=doctor 醫(yī)生
42. sorta=sort of 一種...
43. outa=out of ...之外
44. thx=thanks
45. gtg=gotta go 表示要走了
46.lol=laugh of lot 英文聊天中出現(xiàn)頻率的幾個詞之一，其實就是彪悍的笑，如果你不打haha的話，這個lol也可以表示大笑，并且三個字母組合起來的圖案就如某*笑的嘴，很是生動。
