If you can use it, here is a context clues worksheet on the noun cant. It means, within the context the sentences in this document supply, “affected singsong or whining speech” and especially “the expression or repetition of conventional or trite opinions or sentiments; especially : the insincere use of pious words.” I don’t know whether students need to know this word or not; I am fairly confident, however, that whenever a mass shooting occurs in this country, and politicians take to Twitter to intone about their thoughts and prayers, that we hear cant in its purest form.
