- Shaped like a lance: Having a long, narrow form that tapers to a point at one or both ends, resembling the blade of a spear or lance.
Usage
- The term "lance-shaped" is primarily used in descriptive contexts, especially in botany, biology, and general description to characterize the form of leaves, petals, or other objects.

- It can be modified by adverbs like "broadly" or "narrowly" to indicate specific proportions (e.g., "broadly lance-shaped").
