Etymology of “Fly off the Handle”

The phrase “fly off the handle” dates back to the 19th century in the United States. It is derived from the world of woodworking and refers to an axe or hammer head coming loose from the handle and flying off.

Imagine someone using an axe or hammer, and suddenly the metal head detaches from the wooden handle. This situation is dangerous and unpredictable, much like someone losing their temper without warning.

Breakdown:

1. Fly: In this context, it means to suddenly and rapidly move.
2. Off the Handle: Refers to the tool’s head becoming dislodged and out of control.

Meaning:

The phrase is a metaphor for losing one’s temper or becoming uncontrollably angry, similar to how a tool’s head flies unpredictably when detached. When someone “flies off the handle,” their anger bursts out suddenly, often without warning.

Example:

• “When I told him about the mistake, he flew off the handle and started shouting.”

Analogy:

Think of a fly off the handle moment like a shaken soda can suddenly bursting open when you least expect it. Just as the soda flies everywhere uncontrollably, someone’s temper can burst out suddenly.
