lagomorph
C2Technical/Scientific
Definition
Meaning
A mammal of the order Lagomorpha, which includes rabbits, hares, and pikas, characterized by two pairs of upper incisor teeth, one behind the other, and a strictly herbivorous diet.
In non-technical contexts, it can refer generally to rabbit-like animals. In taxonomy, it represents a specific mammalian order distinct from rodents, with which they were once incorrectly classified.
Linguistics
Semantic Notes
Primarily a taxonomic/zoological term. Laypeople are more likely to use 'rabbit', 'hare', or 'pika'. It is often used to emphasize the taxonomic distinction from rodents.
Dialectal Variation
British vs American Usage
Differences
No significant differences in meaning or usage. The term is equally rare and technical in both varieties.
Connotations
Neutral, scientific. No regional connotations.
Frequency
Extremely low-frequency in general language in both regions, limited to scientific/biological contexts.

Examples
By CEFR Level
- A rabbit is a kind of animal called a lagomorph.
- Rabbits and hares are both types of lagomorph.
- Unlike rodents, lagomorphs have two pairs of upper incisors and are strictly herbivorous.
- The palaeontological record shows that early lagomorphs diverged from other placental mammals around the late Palaeocene.
Learning
Memory Aids
Mnemonic
Think of 'LAGO' (like lake) and 'MORPH' (shape/form). Picture a rabbit MORPHING its shape by a LAKE. The two 'g's in 'lagomorph' can remind you of the two pairs of gnawing (gnawing starts with 'g') incisors.
Conceptual Metaphor
Taxonomic precision. The term is often used metaphorically to represent 'correct classification' or 'splitting from a larger, incorrect group' (as lagomorphs were split from rodents).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate as 'грызун' (rodent). The correct direct translation is 'зайцеобразные', but the simpler 'кролик или заяц' (rabbit or hare) is often sufficient in non-scientific contexts.
Common Mistakes
- Misspelling as 'lagamorph' or 'logomorph'.
- Pronouncing the 'g' as soft /dʒ/ (like in 'gem') instead of hard /ɡ/.
- Using it as a synonym for 'rabbit' in everyday talk, which sounds overly technical.

FAQ
Frequently Asked Questions
No. Rabbits are lagomorphs. They were once classified as rodents but were separated into their own order, Lagomorpha, due to key anatomical differences, most notably their two pairs of upper incisors.
The order includes two living families: Leporidae (rabbits and hares) and Ochotonidae (pikas).
You would primarily use it in a scientific, academic, or very specific enthusiast context (e.g., biology class, a veterinary discussion, a nature documentary focusing on taxonomy). In everyday conversation, 'rabbit' or 'hare' is perfectly adequate.
In British English: /ˈlaɡə(ʊ)mɔːf/ (LAG-oh-morf). In American English: /ˈlæɡəˌmɔːrf/ (LAG-uh-morf). The first 'g' is always a hard /ɡ/ sound.
