LetX* be a free monoid over an alphabetXandWbe a finite language overX. LetS(W) be the Rees quotientX*/I(W), whereI(W) is the ideal ofX* consisting of all elements ofX* that are not subwords ofW. ThenS(W) is a finite monoid with zero and is called the discrete syntactic monoid ofW.Wis called finitely based if the monoidS(W) is finitely based. In this paper, we give some sufficient conditions for a monoid to be non-finitely based. Using these conditions and other results, we describe all finitely based 2-limited words over a three-element alphabet. Furthermore, an explicit algorithm is given to decide that whether or not a 2-limited word in which there are exactly two non-linear letters is finitely based.
