agouti
C2+Scientific/Zoological
Definition
Meaning
A rodent native to Central and South America and the Caribbean, resembling a large guinea pig with longer legs and coarse grizzled fur.
The grizzled pattern of coloration in animal fur, alternating dark and light bands on each hair, seen in many mammals including the rodent and also dogs, cats, and horses.
Linguistics
Semantic Notes
Primarily a technical zoological term. In common usage, the word is almost exclusively used to refer to the animal. The extended meaning referring to the fur pattern is predominantly used in genetics, animal breeding, and specialized fields like equine or canine coat color description.
Dialectal Variation
British vs American Usage
Differences
No significant differences in meaning or spelling. Both varieties primarily use the term in zoological contexts.
Connotations
Neutral scientific/zoological term in both dialects.
Frequency
Extremely low frequency in general language for both. Slightly higher potential exposure in the UK due to historical naturalist literature. In the US, may be encountered in zoos, exotic pet circles, or biology texts.

Usage
Context Usage
Academic
Used in biology, zoology, genetics, and ecology papers discussing Neotropical fauna or mammalian coat color genetics.
Everyday
Virtually never used in casual conversation outside specific contexts like visiting a zoo with a knowledgeable guide.
Technical
Core term in mammalogy. Also used in genetics (agouti signaling protein, ASIP gene) and animal husbandry/breeding for describing specific coat patterns in livestock and pets.

By Part of Speech
adjective
British English

Examples
By CEFR Level
- At the zoo, we saw an agouti, which looks like a large rodent.
- The biologist explained that the agouti's fur has a unique banded pattern on each hair strand.
- Agoutis are important seed dispersers in their rainforest habitats.
- The expression of the agouti gene regulates the distribution of pigment in mammalian hair, resulting in the characteristic grizzled appearance.
- Despite its ecological significance, the agouti remains one of the lesser-known Neotropical mammals outside specialist circles.
Learning
Memory Aids
Mnemonic
Think: 'A GOOut and TIE it up?' Sounds silly, but connects to the animal you might see on a go-out (outing) in the tropics. Or link 'gouti' to 'coati' (another tropical animal).
Conceptual Metaphor
N/A for the animal. For the pattern: 'AGOUTI IS A BANDED CYLINDER' (describing the individual hairs).

Common Pitfalls
Translation Traps (for Russian speakers)
- May be transliterated as 'агути' which is correct. Do not confuse with 'агouti' looking like a Russian word; it is a direct borrowing.
Common Mistakes
- Mispronunciation: /ˈæɡəʊtaɪ/ or /əˈɡaʊti/. Correct is /əˈɡuːti/.
- Misspelling: 'agoutti', 'agouty'.
- Assuming it's a type of cat or rabbit.

FAQ
Frequently Asked Questions
No, it is not a true rat. It is a rodent in the family Dasyproctidae, distinct from rats (Muridae). It is more closely related to guinea pigs and capybaras.
In some regions, yes, but they are exotic pets requiring specialised care. They are wild animals at heart and need ample space and specific diets. Ownership is illegal or restricted in many places.
It is a coat colour pattern where each hair has alternating bands of light and dark pigment, giving a 'peppered' or 'grizzled' appearance, common in breeds like the Norwegian Elkhound or Siberian Husky.
It is pronounced /əˈɡuːti/ (uh-GOO-tee), with the stress on the second syllable and a long 'oo' sound, identical in both British and American English.
