percontative

Some [grammatical writers] call these affections of the verb moods; others call them divisions, qualities, states, species, &c.; and as to the various appellations of each mood we have the personative and impersonative, the indicative, declarative, definitive, modus finiendi, modus fatendi, the rogative, interrogative, requisitive, percontative, assertive, enunciative, vocative, precative, deprecative, responsive, concessive, permissive, promissive, adhortative, optative, dubitative, imperative, mandative, conjunctive, subjunctive, adjunctive, potential, participial, infinitive, and probably many others.

‘Perfect Dicibles are of various sorts: Interrogative; Percontative; Adjurative; Optative; Imprecative; Execrative; Substitutive; Compellative; Hypothetical; and, lastly, Dubious.’

Destined for internal consumption, these three words nevertheless provoked the reply which you see here: who doesn’t? With an interrogation point, for the reply was percontative.
