弓

Primary: The bow (weapon).

Extended: Curved or arched. Used as a descriptor of shape when applied to objects, terrain, or anatomical features (e.g., eyebrows); in these contexts, it often implies a structural arc or a degree of tension rather than a random bend.

Functions primarily as a noun (the object) or an attributive adjective (bow-shaped/curved). It does not typically function as a verb meaning "to bend" (see 屈 or 彎).

In military contexts, distinguish strictly between the simple bow (弓) and the mechanical crossbow (弩). Use of 弓 over 弩 may indicate traditional archery as opposed to mechanical artillery.

When the context is ambiguous, determine if the author is referencing the tool (the weapon) or the quality (the arc/tension). The underlying semantic theme is often elasticity or structural tension.
