"Markov chain" might mean: * a kind of stochastic model * a "naive" realization of that model which directly counts frequencies of N-dimensional vectors This naive implementation is sometimes used for language modeling, e.g. for the purpose of compression. So people might think you mean that particular implementation rather than a theoretical model. This sort of a description can be unhelpful.
