handler

Synonym discussion
Sense: noun/3
All four words name people who work closely with animals, but the focus differs. A handler controls an animal during real work or a competition, walking it on a lead and giving commands the audience or task requires; police-dog and show-dog work is typical. A trainer focuses on teaching the animal new skills over weeks or months, and may never appear with the animal in public. A keeper looks after animals' daily needs (food, cleaning, health), most often in zoos or wildlife parks, and is not necessarily a teacher. A groom cares specifically for horses, including washing, brushing and saddling, but does not usually compete with them. For example, a dog might learn tricks from a trainer, perform them in the ring with a handler, and sleep in kennels cleaned by a keeper.

Etymology
Built in English from the verb 'handle' plus the agent ending '-er', meaning literally 'a person who handles something'. The verb itself goes back to Old English 'handlian', from 'hand', and originally meant simply to touch or manage with the hand. From the 16th century onwards, English steadily widened 'handle' from physical touch to mental and social control (handling money, handling people, handling a problem), and 'handler' followed each step — first the airport and warehouse senses, later the spy, political and boxing-corner roles in the 20th century.
