The negation operator ! always returns false or true. The conjunction operator እና returns its first argument if this value is false or nil; otherwise, እና returns its second argument. The disjunction operator ወይም returns its first argument if this value is different from ባዶ and false; otherwise, ወይም returns its second argument. Both እና and ወይም use short-circuit evaluation; that is, the second operand is evaluated only if necessary. Here are some examples:

• ወይም

አውጣ 10 ወይም 20; // 10
አውጣ 10 ወይም ባዶ; // 10
አውጣ ባዶ ወይም 10; // 10

• እና

አውጣ 10 እና 20; // 20
አውጣ 10 እና ሀሰት; // ሀሰት
አውጣ ሀሰት እና 10; // ሀሰት

• !

አውጣ !ሀሰት; // እውነት
አውጣ !እውነት; // ሀሰት
