red pepper
B1Neutral, common in culinary, everyday, and informal contexts.
Definition
Meaning
The fruit of various plants of the genus Capsicum, typically red when ripe, used as a vegetable or spice. It can refer broadly to both sweet bell peppers and hot chili peppers.
Can refer specifically to the ripe, red form of the bell pepper (Capsicum annuum) or to various hot, red chili peppers. Also denotes a powdered spice made from dried, ground hot red peppers.
Linguistics
Semantic Notes
Context is crucial. Without modifiers, 'red pepper' can be ambiguous between sweet and hot varieties. Often clarified by collocations (e.g., 'red bell pepper', 'crushed red pepper').
Dialectal Variation
British vs American Usage
Differences
In British English, 'pepper' alone often refers to the bell pepper/capsicum. 'Red pepper' thus usually means the sweet, large, red variety. In American English, 'red pepper' can more frequently refer to hot chili peppers or their flakes/powder, especially in phrases like 'red pepper flakes'.
Connotations
UK: Primarily a sweet vegetable. US: Can imply either a sweet vegetable or a source of heat/spice, depending on context.
Frequency
Term is common in both varieties. The sweet vegetable is more commonly called 'red pepper' in the UK; in the US, 'red bell pepper' is often used for clarity.

Remember the colour: RED for ripe and sometimes for heat (like a warning). PEPPER for the plant family, which includes both sweet and hot varieties.
Conceptual Metaphor

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- The Russian 'красный перец' is equally ambiguous, covering both sweet and hot types. Be aware that English recipes may specify 'bell pepper' or 'chili' to avoid confusion.
- The spice 'paprika' is often called 'красный перец' in Russian, but in English, 'paprika' is more specific and 'red pepper' can be the whole vegetable or a hotter ground spice.
Common Mistakes
- Using 'red pepper' to mean black pepper (Piper nigrum) that is red in colour.
- Assuming 'red pepper' always refers to the sweet variety in an American culinary context.

FAQ
Frequently Asked Questions
Not exactly. 'Red pepper' is a broad term. It can include red chili peppers (which are hot) but also red bell peppers (which are sweet). The context usually clarifies.
Yes, but the flavour profile will change. Green peppers are less sweet and more bitter than ripe red peppers. For a similar sweetness, use a yellow or orange bell pepper.
It is typically made from dried, hot red chili peppers (like cayenne or birds eye chilies) that are crushed into flakes. It is used as a spicy condiment.
The heat comes from the compound capsaicin, which is present in varying amounts in different cultivars. Bell peppers have been bred to have negligible capsaicin, while chili peppers produce it.
