Teh is an Internet slang neologism most frequently used as an English article, based on a common typographical error of "the". Teh has subsequently developed grammatical usages distinct from the.^[1] It is not common in spoken or written English outside technical or leetspeak circles, but when spoken, it is pronounced /tɛ/, /tə/, or /teɪ/.^[2]

Teh originates from the common typo of the, as might both occur and remain uncorrected when a person was typing rapidly prior to the widespread availability of autocorrect helper applications, and has become conventionalized in a variety of contexts.

In addition, it is a standard feature of leetspeak^[3] and can be used ironically^[4] or to mock someone's lack of "techie" knowledge or skills, as an insult, or to reinforce a group's elitism;^[2] cf. eye dialect.
