A person who has charge of or works in an avenary; someone who manages oat storage or processing.
From 'avenary' plus the agent suffix '-er' (one who does something). This occupational title emerged in medieval times to describe workers in grain management.
Medieval job titles like 'avener' were incredibly specific—instead of just 'worker,' people had titles that told you exactly what they did, making it easy for historians to map out entire occupational hierarchies and understand how specialized medieval societies actually were.
