roundworm
C1Technical / Scientific
Definition
Meaning
A type of parasitic worm with a long, cylindrical, unsegmented body that commonly infects the intestines of humans and other animals.
By extension, a member of the nematode phylum Nematoda, which includes both parasitic and free-living species found in virtually every environment.
Linguistics
Semantic Notes
The term is primarily used in biology, veterinary medicine, and human parasitology. In common parlance, it may be used generically to refer to intestinal worms, but technically it specifies a specific group (nematodes).
Dialectal Variation
British vs American Usage
Differences
No significant difference in meaning or usage. Both varieties use the term identically in technical contexts.
Connotations
Neutral, clinical, and descriptive in both varieties.
Frequency
Equally low-frequency in general language, but standard in relevant scientific fields.

Context Usage
Business
Rarely used, except potentially in the pharmaceutical or pet care industries.
Academic
Common in biology, medicine, veterinary science, and parasitology papers and textbooks.
Everyday
Used when discussing pet health, childhood infections, or gardening/soil biology in a non-specialist way.
Technical
The standard term in parasitology and veterinary diagnostics for nematode infections.
Examples
By CEFR Level
- The vet said my puppy has roundworms.
- Children playing in contaminated soil can sometimes get a roundworm infection.
- The most common human roundworm, Ascaris lumbricoides, affects millions worldwide.
- Nematology, the study of roundworms, reveals their incredible diversity, from soil-dwelling decomposers to debilitating parasites.
Learning
Memory Aids
Mnemonic
Think of a worm that is 'round' in cross-section, unlike flatworms which are flat. It's a simple descriptor of its shape.
Conceptual Metaphor
PARASITE AS INVADER / INFECTION AS ENEMY (e.g., 'fighting a roundworm infestation').
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid calquing as 'круглый червь' in all contexts. While technically correct, the more common specific terms are 'нематода' (technical) or 'аскарида' for a common type (Ascaris).
Common Mistakes
- Using 'roundworm' to refer to all parasitic worms (e.g., tapeworms, which are flatworms).
- Misspelling as 'round worm' (should be one word or hyphenated: 'round-worm').

FAQ
Frequently Asked Questions
No. While many well-known roundworms are parasites, the phylum Nematoda includes countless free-living species in soil and aquatic environments.
Some pet roundworms (like Toxocara) can infect humans, especially children, causing a condition called visceral larva migrans, but human-to-human transmission of the common human roundworm (Ascaris) is more typical.
Roundworms (nematodes) have cylindrical, unsegmented bodies and a complete digestive tract. Tapeworms (cestodes) are flat, segmented, and lack a digestive system, absorbing nutrients directly.
It is a standard common name used in formal scientific contexts (e.g., 'roundworm infection'), but the more precise taxonomic term is 'nematode'.
