The phrase "set in concrete" is an idiomatic expression that means something is fixed, unchangeable, or permanent. It is derived from the literal process of setting or placing objects in concrete, which once dried and hardened, becomes solid and immovable.
Metaphorically, this phrase is used to describe a decision, plan, or idea that is firmly established and cannot be altered easily. It implies that the course of action has been finalized, and there is little or no room for modification or negotiation. When an idea or concept is "set in concrete," it suggests that it is considered absolute or inflexible, lacking any potential for adaptation or evolution.
This metaphorical usage often carries a sense of permanency and irrevocability, conveying the notion that the matter at hand has been settled definitively and is unlikely to be revised or reversed. It can be applied to various contexts, including business, politics, and personal relationships, where a rigid stance or an unyielding attitude is observed.
However, it is important to note that while the phrase implies a high degree of permanence, it does not necessarily signify an absolute immutability. Just as concrete can be broken or removed, ideas or plans can be revised or changed over time, albeit with some effort. Thus, the phrase "set in concrete" serves as a vivid way to convey the notion of steadfastness and difficulty in modifying established decisions or plans.
