### Core Meaning & Semantic Range
The Greek word **ásophos**, represented by `{{G781}}`, is defined as **unwise**. It is formed from a negative particle and the word for wise, `σοφός`. Appearing just **1 times** in **1 unique verses**, its significance comes from its direct and powerful contrast with wisdom. In its sole use, it is translated as **fool**.
### Biblical Occurrences & Contextual Analysis
The single biblical appearance of `{{G781}}` is in [[Ephesians 5:15]], where it is used to establish a clear behavioral distinction. The verse commands believers to "walk circumspectly, not as **fools**, but as wise." Here, `ásophos` is not merely an abstract concept but is tied to the practical, daily conduct—the "walk"—of a believer. It represents a manner of living that lacks carefulness and spiritual insight.
### Related Words & Concepts
Several related words in its immediate context clarify the meaning of `{{G781}}`:
* `{{G4680}}` **sophós** (wise): This is the direct antonym of `ásophos`. Its use in the same phrase, "not as fools, but as **wise**" [[Ephesians 5:15]], creates a stark and intentional contrast, presenting two mutually exclusive paths.
* `{{G4043}}` **peripatéō** (to live, deport oneself, follow): This word defines the action being qualified as either wise or foolish. The command concerns how believers **walk**, or conduct their lives, making the choice between wisdom and foolishness a practical matter of daily living [[Ephesians 5:15]].
* `{{G235}}` **allá** (but, contrariwise): This conjunction is the pivot point in the phrase, establishing the opposition. It mandates a rejection of the `ásophos` way of life in favor of the `sophós` one, as seen in the command to walk "not as fools **but** as wise" [[Ephesians 5:15]].
### Theological Significance
The theological weight of `{{G781}}` is concentrated in its single, forceful application.
* **A Call to Mindful Conduct:** The term is used within a command to "See then that ye walk circumspectly" [[Ephesians 5:15]]. This frames the avoidance of being `ásophos` as a matter of diligent, intentional living, not passive existence.
* **An Unambiguous Contrast:** By placing `ásophos` in direct opposition to `sophós`, the text presents a clear dichotomy. There is no middle ground offered; a believer's walk is either wise or unwise.
* **Negative Definition of Wisdom:** The instruction not to be like **fools** serves to sharpen the call to be wise. It is a warning that defines the Christian walk by what it must not be, thereby compelling believers to actively pursue the characteristics of a life led with wisdom.
### Summary
In summary, while `{{G781}}` is one of the rarer words in the New Testament, its role is pivotal. As **unwise** or **fool**, it functions as a critical negative benchmark. Its sole use in Scripture serves not just to describe a state, but to deliver a command against it, framing the Christian life as a deliberate "walk" that must consciously reject foolishness and embrace the path of wisdom.
