--1 The Ontology of the Phrasebook
--2 Syntactic Structures of the Phrasebook
-- This module contains phrases that can be defined by a functor over the
-- resource grammar API. The phrases that are likely to have different implementations
-- are in the module Words. But the distinction is not quite sharp; thus it may happen
-- that the functor instantiations make exceptions.
abstract Sentences = Numeral ** {
