A very short written way of saying 'thanks'.

A very short written way of saying 'thanks'這是「thanks（謝謝）」很短的書寫寫法。

You use it in text messages, chat apps, and quick emails between friends or close colleagues — never in a letter, a report, or a message to a teacher, a customer, or a boss you do not know well. It is not really a word you say out loud; if you read it aloud you just say 'thanks'.

You use it in text messages, chat apps, and quick emails between friends or close colleagues你會在朋友或熟同事之間的簡訊、聊天app、和簡短email裡用它—— never in a letter, a report, or a message to a teacher, a customer, or a boss you do not know well但絕對不會用在信件、報告、或寫給老師、客戶、還不熟的老闆的訊息裡。It is not really a word you say out loud這不是一個你會唸出聲的字； if you read it aloud you just say 'thanks'如果要唸出來，你就直接說 'thanks'。

It belongs to the same family of typing shortcuts as 'pls' (please), 'ur' (your/you're) and 'ttyl' (talk to you later), and like them it can be written with small letters too: thx.

It belongs to the same family of typing shortcuts as 'pls' (please), 'ur' (your/you're) and 'ttyl' (talk to you later)它跟 'pls'（please，請）、'ur'（your/you're，你的／你是）、'ttyl'（talk to you later，晚點聊）是同一類打字縮寫， and like them it can be written with small letters too: thx而且跟它們一樣可以全部用小寫：thx。

People often stretch it for warmth — 'thx!!', 'thx so much' — because bare 'thx' can read as a little cold or rushed, the way a one-word reply does.

People often stretch it for warmth人們常常會把它拉長來表示熱情——像 'thx!!', 'thx so much''thx!!'、'thx so much'——because bare 'thx' can read as a little cold or rushed因為單獨一個 'thx' 讀起來可能有點冷淡或匆忙， the way a one-word reply does就跟只回一個字的感覺一樣。

Two things to know: 'THX' in capital letters is also a famous cinema sound company, so on a film poster or a speaker it means something completely different; and in a work chat, whether 'thx' feels friendly or lazy depends entirely on the office, so watch what other people write before you use it.

Two things to know有兩件事要知道： 'THX' in capital letters is also a famous cinema sound company全部大寫的 'THX' 也是一家知名的電影音效公司， so on a film poster or a speaker it means something completely different所以出現在電影海報或喇叭上時，意思完全不一樣； and in a work chat而在工作聊天裡， whether 'thx' feels friendly or lazy depends entirely on the office 'thx' 聽起來是親切還是敷衍，完全要看公司的文化， so watch what other people write before you use it所以用之前先看看別人怎麼打。
