The Winkelhaken (German: [ˈvɪŋkəlˌhaːkən], "angular hook"), also simply called a hook, is one of five basic wedge elements appearing in the composition of signs in Akkadian cuneiform. It was realized by pressing the point of the stylus into the clay.

A single Winkelhaken corresponds to the sign U (Borger 1981 nr. 411, Borger 2003 nr. 661), encoded in Unicode at code point U+1230B 𒌋.

other signs consisting of Winkelhaken:

• A Glossenkeil (Borger nr. 378) is a cuneiform character, consisting of either two Winkelhaken (U+12471 𒑱), or of two parallel short diagonal wedges (U+12472 𒑲, similar to GAM), Borger 2003 nr. 592, which serves as a sort of punctuation, as it were as quote sign, marking foreign words or names, or as separation mark, transliterated as a colon ':'.
