Grainer → The word 'grainer' comes from the Old French 'graine' (meaning seed or grain) combined with the suffix '-er' (meaning a person who). A grainer is a person who deals with or works with grain.
Think of someone who works with 'grain' ('graine') — the '-er' just means a person. A grainer is someone who handles grain.
