What word is used to describe something that is withered or dry?

The term that describes something that is withered or dry is "sere." This word is often used in botanical contexts to refer to vegetation that has lost moisture and vitality, typically as a result of drought or other environmental conditions. When plants or landscapes are described as sere, it indicates that they appear parched, lifeless, and devoid of the lushness associated with healthy growth. This term emphasizes the effect of desiccation on living organisms, reflecting their inability to thrive in adverse conditions.

The other terms provided do not convey the same meaning. "Sodden" refers to something that is soaked or saturated, often implying excess moisture rather than dryness. "Serrated" describes a jagged edge or a saw-like appearance, which is primarily used in the context of shapes or forms rather than moisture content. "Spurn" means to reject or disdain something, which relates to actions or attitudes and does not pertain to physical conditions of dryness or withering. Thus, "sere" is the most appropriate choice for describing something that is withered or dry.
