A sarcasm mark or sarcasm point identifies text as being derogatory or ironic. Although never known traditionally in Ethiopia, a sarcasm mark has been introduced in the Unicode set of Ethiopian characters Ethiopic languages,[1] (¡). Its use is not yet documented in writing Amharic or any other Ethiopian language.
It is not a standard form of punctuation in English. If a mark for such a purpose were proposed and became widely accepted, it would serve a similar purpose to the French irony mark in helping the reader to identify and interpret specific types of non-literal language.
In some cases, an exclamation mark in brackets is used to serve a similar purpose in English.
