The class of commutative dually residuated lattice ordered monoids ( D R -monoids) contains among others Abelian lattice ordered groups, algebras of Hájek’s Basic fuzzy logic and Brouwerian algebras. In the paper, a unary operation of negation in bounded D R -monoids is introduced, its properties are studied and the sets of regular and dense elements of D R -monoids are described.
