What does serrulate mean?
Serrulate is a specialized adjective meaning finely or minutely serrated, describing an edge or surface bearing very small, tooth-like projections. It is used especially in botany and zoology for features such as leaf margins, jaws, teeth, and other finely divided structures. Unlike the broader word serrate, which can refer to saw-like teeth of any readily visible size, serrulate emphasizes the minute scale of the serrations. The distinction is therefore useful when describing a feature whose tiny teeth can be seen only with magnification or careful observation. Serrulate is uncommon outside specialist writing, but within its fields it provides precise vocabulary for differentiating degrees of serration. It is related in both meaning and origin to serrate and serration, all of which derive from the Latin word for a saw.
