Putting aside that the use of 'thx' is bad, and it isn't really a word. Would 'thx' be considered a contraction or abbreviation?

Contraction: a shortened version of the written and spoken forms of a word, syllable, or word group, created by omission of internal letters (actually, sounds).

The page also states that a contraction "shouldn't be confused with an abbreviation or acronym. My logic says that it would be an abbreviation since a contraction would also change the phonetic version of the word while an abbreviation does not.

  • I suggest it is a contraction of the phonetic, 'thanx'. Note that some people consider this to be a thank you followed by a kiss. Kisses are commonly appended to a missive in the form of a letter 'X'. – chasly from UK Oct 1 '15 at 17:11

Abbreviation. Rather like "Xmas", "thx" is a written, not a spoken, shorthand. The word is still pronounced "Thanks".


Thx is an abbreviation of "thanks". The 'x' at the end replaces the 's', and when spoken aloud, sounds the same as the original word.

The word "thanks", is actually a plural of "thank you", so if you were given "many thanks", you were given many "thank yous".

  • Small nitpick, but the "x" replaces the "ks", same as in "thanx". – Laurel Feb 4 '18 at 21:39
