drupe
C2Technical/Scientific
Definition
Meaning
A type of fruit with a fleshy outer part surrounding a hard shell (stone or pit) containing a single seed.
In botany, a simple fruit derived from a single carpel, typically indehiscent, characterized by the three distinct layers: exocarp (skin), mesocarp (flesh), and endocarp (hard pit).
Linguistics

The term is primarily used in botanical contexts. In everyday language, specific examples (peach, plum, cherry) are more common than the category name.

By Part of Speech
adjective
British English
- The drupaceous layer was carefully dissected.

Learning
Memory Aids

A DRUPE has a hard inner PIT, like a PRUNE. Think DRUPE = DRU (like 'drew' a circle) around a P (the pit).
Conceptual Metaphor
ARMOUR/CONTAINER (a protective, hard shell containing a valuable seed).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation to 'костянка' unless in a strict botanical context. In everyday Russian, specific fruit names are used, not the category.
Common Mistakes
- Confusing drupes with berries (e.g., calling a cherry a berry).
- Using 'drupe' in casual conversation instead of the common fruit name.

FAQ
Frequently Asked Questions
Yes, botanically a coconut is a drupe, specifically a fibrous drupe. Its hard shell is the endocarp (pit), the fibrous husk is the mesocarp, and the smooth outer skin is the exocarp.
A drupe has a single hard stone or pit surrounding the seed (e.g., peach). A true berry has multiple seeds embedded in a fleshy pulp without a hard pit (e.g., tomato, grape).
It's very uncommon. It's better to use the specific fruit name (e.g., 'plum,' 'cherry') or the more familiar term 'stone fruit.'
The edible part we call an almond or walnut is the seed *inside* the drupe's stone. The outer fleshy part of an almond drupe is not typically consumed.
