Three Akan institutions are made of language, and none of them can be explained without it.
The first is the day name. Every Akan child receives a name fixed by the day of the week on which it was born, in a matched pair of male and female forms, and the name is not decorative: it belongs to an account of the person in which the kra, the soul portion that comes from Nyame, arrives on that day. Kwame, Kofi, Yaa and Akosua are ordinary Akan words before they are anybody's name, and they travelled with the Atlantic trade, which is why Akan day names surface in the Caribbean and the Americas attached to people whose descendants no longer speak the language.
The second is drum language. The Asante talking drums do not send a code. They reproduce the tone and rhythm of Akan speech itself, so that a drummed text is the language spoken by another instrument, and a listener who knows the conventional phrases hears sentences. The court drums carry praise texts, genealogies and the announcements of state, and the practice depends entirely on Akan being tonal.
The third is adinkra. Each stamped symbol stands for a proverb or a saying, and the symbol is an abbreviation of the sentence rather than a picture of a thing. Gye Nyame, the best known of them, is an Akan clause. Read the symbols without the language and you have a design; read them with it and you have a body of aphorism about power, mortality, patience and God.
