endocarp
C2Technical/Scientific
Definition
Meaning
The hard, inner layer of the pericarp (fruit wall) that surrounds the seed(s) in some fruits.
In botany, the innermost layer of a fruit's pericarp, often stony or leathery, forming the pit or stone in drupes like peaches, plums, or cherries.
Linguistics
Semantic Notes
A highly specific botanical term. It is a meronym (part) of the pericarp, which consists of three layers: exocarp (skin), mesocarp (flesh), and endocarp (stone/pit). Not used in everyday language.

Examples
By Part of Speech
adjective
British English
- The endocarpal layer was examined.
- Endocarpic thickness varies.
American English
- Endocarpal tissue was analyzed.

Examples
By CEFR Level
- A peach has a hard stone inside.
- The hard stone of a plum is called the endocarp.
- In drupes, the endocarp becomes lignified to form a protective pit around the seed.
- Botanists classify fruits partly based on the texture of the endocarp.
Learning
Memory Aids
Mnemonic
Think: ENDO (inside) + CARP (fruit) = the inside layer of the fruit.
Conceptual Metaphor
The endocarp is the fruit's 'armour' or 'safe' for the seed.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'эндокарпий' (direct equivalent, formal) and 'косточка' (everyday term for pit/stone). 'Эндокарпий' is the exact scientific term, while 'косточка' is the common word.
Common Mistakes
- Using 'endocarp' to refer to the entire seed or the whole hard centre of a fruit. It is specifically the tissue layer *forming* the stone.
- Confusing it with 'endodermis' (a root tissue).

What is the endocarp?
FAQ
Frequently Asked Questions
No. The endocarp is the hard tissue layer that *surrounds* the seed. In a peach, the seed is inside the stony endocarp (the pit).
Drupes or stone fruits: peaches, plums, cherries, apricots, olives, and mangoes. Also in coconuts (the hard shell).
It would sound very technical and unusual. Use 'stone', 'pit', or 'seed' (though 'seed' is not technically accurate for the stone itself) instead.
The pericarp has three layers: exocarp (outer skin), mesocarp (middle, often fleshy part), and endocarp (inner layer, often hard).
