What does hexapod mean?
A hexapod is an arthropod with six legs, and the word is most strongly associated with insects, which nearly always have three pairs of legs. In modern biological classification, the term can have a somewhat broader reach, encompassing certain non-insect six-legged arthropods as well. It comes from Greek elements meaning “six” and “foot,” making the name a direct description of the animal’s characteristic anatomy. Hexapod is chiefly used in zoology, entomology, and related technical writing, while everyday discussion normally uses “insect” when that is the intended category. The word is also found in environmental and agricultural contexts, such as “hexapod insecticide,” where it describes an insecticide aimed at six-legged pests. Although not itself especially common outside specialist writing, it is useful because it names the shared six-legged form without necessarily committing the writer to the narrower category of insects.
nounA six-legged arthropod, especially an insect. In modern zoology, the term may also include other six-legged arthropods, such as springtails.
- Any six-legged arthropod; in biological usage, especially a member of the broader grouping that includes insects and certain related non-insect arthropods.
"The insect is the most familiar hexapod, although the group also includes several non-insect arthropods."
"The entomologist identified the unfamiliar hexapod as a small, fast-moving insect."
"Many species of hexapod possess three pairs of legs and a segmented body."
The standard plural is formed by adding “-s” to the noun.
"Many hexapods possess three pairs of legs."
A hexapod is literally a six-footer, but its three pairs of legs helped make insects the most diverse animals on Earth.

Where does hexapod come from?
The word “hexapod” comes from Greek hexa-, meaning “six,” and pous or pod, meaning “foot.” Its formation reflects the long-established zoological description of insects and related arthropods as animals with three pairs of legs. Latinized forms of the Greek compound supported its development as a scientific English term, while modern usage can include some non-insect hexapods.

How hexapod is actually used
This is primarily a technical zoological term. In general writing, “insect” is more natural when that narrower meaning is intended. It is rarely used informally for a person or animal with six legs.
