person managing things or animals
A person whose job is to move, control, or take care of certain things or animals.
用法パターン：
a [type] handler; a handler for [something]
よくある間違い：
Learners sometimes use "handler" instead of "handle" as a verb, saying *"He will handler the bags"* instead of "He will handle the bags." Remember: "handler" is a noun (a person), and "handle" is the verb (the action).
類義語
operator (suggests someone who uses or controls a machine or system rather than caring for animals.)
|
attendant (focuses more on looking after people or things, often in service jobs.)
|
caretaker (emphasizes looking after and protecting, especially animals or property, less about moving items.)
対義語
passenger (at an airport or station, the passenger is served, while the handler does the moving work.)
|

2
manager of a public figure
A person who plans and controls what a famous person does and how other people see them.
用法パターン：
[someone]'s handler; a political handler for [someone]
よくある間違い：
Learners may confuse this with a general "manager" in a company. A "handler" in this sense usually controls a public figure’s access, image, and communication, especially in politics, entertainment, or media, not a normal office team.
類義語
manager (a broader term; can manage business, money, or career, not only public image and access.)
|
handler (often suggests tight control over access and messaging, sometimes with a slightly negative tone.)
|
fixer (informal; suggests someone who solves problems behind the scenes, sometimes in questionable ways.)
対義語
independent (a public figure described as independent is seen as acting without handlers controlling their behavior.)

software component for handling events
A piece of computer code that runs when a special event happens, like a click or an error, and deals with that event.
用法パターン：
an [event/error] handler for [something]
よくある間違い：
Some learners think a "handler" in programming is a person. In computing, a handler is a function or piece of code, not a human. Also, do not confuse it with a "handle", which can mean a reference or ID for a resource.
類義語
callback (a common programming term; a function passed to be called later, often used as or by a handler.)
|
listener (emphasizes waiting for events; often used together with or instead of "handler" in event-driven programming.)
|
service routine (older or more formal technical term; focuses on serving a specific low-level event or interrupt.)
対義語
event source (the component that produces events, in contrast to the handler that reacts to them.)

controller of a spy or informant
A person in a police or spy agency who gives orders to a spy or informant and watches what they do.
用法パターン：
[someone]'s handler; a handler for [an informant]
よくある間違い：
Learners may think a spy’s handler is the same as a "bodyguard". A bodyguard protects someone physically, while a handler gives orders, collects information, and manages the spy’s work.
類義語
controller (intelligence jargon; very close in meaning but less common in general speech.)
|
case officer (formal intelligence term for the officer managing human sources.)
対義語
asset (the spy or informant being run is the opposite role to the handler who controls them.)

類義語
playmaker (focuses on creating scoring chances, not only on controlling the ball.)
|
ball handler (standard sports term, usually as a compound; specifically about controlling the ball.)
対義語
