Droner → The word 'droner' is derived from 'drone' (from Middle English 'dron', meaning a male bee or a lazy person) and the suffix '-er' (meaning a person who performs an action). A droner is a person who operates a drone or, informally, someone who drones on in conversation.
Think of a 'drone' as a buzzing device or a lazy bee, and remember that '-er' indicates a person. So, a droner is someone who operates a drone or someone who drones on.
