A person who plays the citole; a medieval musician specializing in the citole or citole-like instruments.
From 'citole' plus '-er' (agent suffix); a person who plays or performs with the citole, similar to how 'lute' becomes 'lutist.'
The '-er' suffix is English's most productive way of creating 'someone who does X'—and from medieval times through today, every instrument gets a player: citolar, lutist, drummer, pianist.
