What does tysm stand for?

The acronym tysm stands for “thank you so much,” and is commonly used internet and texting slang. According to Cyber Definitions, it can also be used sarcastically. This is most commonly used when typing and most people would say the complete phrase “thank you so much” when face-to-face. Over texting and the internet, the abbreviation tysm is very popular.

Where did the term tysm originate?

Tysm originated as chat speak, or SMS text speak, from texting and chatrooms on the early internet. While it is difficult to trace and exact origin of the word, text speak has been around since as early as 1828, according to Visual Thesaurus.

People have been abbreviating language for longer than most people normally imagine, as it feels like something new that came with the advent of the internet. Typing allows people to communicate faster, and it is expected that people will find new ways to shortcut and communicate in even quicker ways.

One of the earliest known abbreviations is “OK,” which originally stood for “oll korrect,” an intentional misspelling of “all correct.” This phrase rose to popularity in the 1830s. Interestingly, this intentional misspellings can still be seen today with internet abbreviations like “thx,” meaning “thanks,” or “kthxbai,” meaning “Okay, thanks, bye.”

Before that, the famous poem “Elegy to the Memory of Miss Emily Kay” is a poem published in 1828 in the London magazine New Monthly. This poem relies heavily on wordplay with abbreviations and requires much deciphering to make sense of these slang words. If a poem today used chat speak, many would probably have an easy time translating the meaning!

Tysm is exclusively used in casual contexts and would never be used formally, in business discussions, or in other less casual settings. Since the terms originated as internet slang and is still predominantly used as such, using tysm in more formal settings is inappropriate. Tysm would be used in conversations where other internet slang is also appropriate, like “ilysm” in place of “I love you so much” or “omg” in place of “oh my goodness.”

Tysm is an appropriate abbreviation to be used between friends or casual acquaintances, or in some circumstances even casual coworkers of the same level via instant messenger or text, or on SMS apps like WhatsApp. For example, via instant messenger, two coworkers may have the following conversation:

Maggie: Hey! Could you send me the company letterhead? Can’t find it on my computer.

Joe: Sure! Sending now!

Maggie: Tysm!

The acronym tysm would never be appropriate to use in formal conversations or negotiations. This should not be used when emailing or conversing for business or other professional matters.
