An àmúlù is an odù whose two legs are different figures, and there are 240 of them: 256 minus the 16 doubles. They are named by naming both legs in order, joined by a hyphen or simply written together — Ọ̀gbẹ̀-Ọ̀yẹ̀kú, Ìwòrì-Òṣé, Òtúrá-Ìrẹ̀tẹ̀ — with the right-hand leg named first. Names are frequently contracted in speech and in print: Ọ̀gbẹ̀-Ọ̀yẹ̀kú is commonly written and said Ọ̀gbẹ̀-Yẹ̀kú, Ìrosùn-Ọ̀gbẹ̀ as Ìrosùn-Ọ̀gbẹ̀, and the Diaspora books often drop the hyphen altogether. The order of the two names is not decoration: Ọ̀gbẹ̀-Ọ̀yẹ̀kú and Ọ̀yẹ̀kú-Ọ̀gbẹ̀ are different odù, two apart in the 256, with different verses.
