Representing Features
Various linguistic features can also be represented fairly concisely with DCGs by providing extra arguments to the functors. For example, consider the following set of DCG rules:
sentence --> pronoun(subject), verb_phrase. verb_phrase --> verb, pronoun(object). pronoun(subject) --> . pronoun(subject) --> . pronoun(object) --> . pronoun(object) --> . verb --> .This grammar allows sentences like "he likes her" and "he likes him", but not "her likes he" and "him likes him".

“It is a tribute to the peculiar horror of contemporary life that it makes the worst features of earlier times—the stupefaction of the masses, the obsessed and driven lives of the bourgeoisie—seem attractive by comparison.”
