thx

thx is an informal abbreviation for thanks used in digital communication. It appears in text messages, chat, forums, and social media where brevity is common. Written in lowercase, it is typically considered casual and friendly, and may be followed by punctuation such as exclamation marks (thx!) for emphasis.

Variants of the shorthand include thnx, thanx, and tx, with ty also used for thanks but representing a different word. The choice among variants often depends on personal preference, platform norms, and the desired level of formality. In most contexts, thx signals a quick, casual acknowledgment rather than a formal expression of gratitude.

Origins and usage notes: thx derives from the word thanks and is part of a broader trend toward abbreviated language in online communication. It became widespread with the rise of SMS text messaging and early internet forums and remains common in informal exchanges. It is generally discouraged in formal writing or professional correspondence, where spelling out "thanks" or "thank you" is recommended.

Disambiguation: uppercase THX refers to the well-known audio/film certification brand THX Ltd. and is not related to the lowercase shorthand thx. In written material, maintaining case can help avoid confusion between casual shorthand and the branded term.
