Here's the breakdown:
* Purse: Historically, purses were the primary way to carry and store money, especially for women.
* Strings: Purses often had strings attached to them, either to tie them closed or to keep them secure.
* Control: The person who controlled the purse and its strings had control over the money within.
Therefore, the idiom "to control the purse strings" means to have control over the finances of a person, organization, or household. It implies the ability to decide how money is spent, who receives it, and in what amounts.
The idiom's origin is rooted in the practical realities of managing finances in the past. The purse, with its strings, symbolized the power and authority associated with financial control.
The idiom is often used to describe:
* Someone in a position of power: For example, a CEO controlling the company's budget.
* Someone who is frugal or careful with money: For example, a parent who manages the household budget.
* Someone who is stingy or unwilling to spend money: For example, a person who is known for being tight-fisted.
