ruzuzu commented on the word magma
"According to Bergman and Hausknecht (1996): "There is no generally accepted word for a set with a not necessarily associative binary operation. The word groupoid is used by many universal algebraists, but workers in category theory and related areas object strongly to this usage because they use the same word to mean 'category in which all morphisms are invertible'. The term magma was used by Serre |Lie Algebras and Lie Groups, 1965|." It also appears in Bourbaki's Éléments de mathématique, Algèbre, chapitres 1 à 3, 1970."
