What does 'textspeak' refer to?

Textspeak refers to the informal and often abbreviated language that is commonly used in text messages and other forms of digital communication. This type of language is characterized by the use of acronyms, abbreviations, and shorthand to convey messages quickly and efficiently, catering to the brevity that the medium of texting typically requires. For example, expressions like "LOL" (laugh out loud) or "BRB" (be right back) exemplify this style, allowing users to communicate effectively within character limits and the fast-paced nature of digital conversations.

The context of the other options highlights that terms used in legal documents, formal letters, or speeches follow more traditional and formal language structures and conventions, which are distinct from the informal nature of textspeak.
