Graphically indistinguishable from U+00A1, Temherte Slaq differs in semantic use in Ethiopia. Temherte Slaq will come at the end of a sentence (vs at the beginning in Spanish use) and is used to indicate an unreal phrase, often sarcastical in editorial cartoons. Temherte Slaq is also important in children’s literature and in poetic use. Debate is needed among Ethiopian scholars to determine if inverted exclamation mark is acceptable.
