The word uncle indicate a compound relation: for a person to be an uncle, he must be a brother of a parent. In algebraic logic it is said that the relation of Uncle (xUz) is the composition of relations "is a brother of" (xBy) and "is a parent of" (yPz).
 U = B P ≡ x B y P z ⟺ x U z . {displaystyle U=BPquad equiv quad xByPziff xUz.}
Beginning with Augustus De Morgan, the traditional form of reasoning by syllogism has been subsumed by relational logical expressions and their composition.
