dialogist

“Alberto Fernandez is a negotiator, pluralist, and dialogist,” said political analyst Ricardo Rouvier,

Irna describes herself as "part mechanic, part psychologist, part dialogist."

Its author is the jolly and companionable John Boynton Priestley, whose works are to be found in every drawing room which calls itself a parlor; its adapter is the glib Benn Levy, who usually specializes in Mayfair comedy; its dialogist is R. C. Sherriff, hitherto noted for his Journey's End.

This truculent sentiment the Dialogist imputes to a Spanish liberal.
