Etymology: "Quadricycle" is a plain compound: "quadri-", from Latin "quadri-" meaning "four" (as in "quadrilateral" or "quadruped"), joined to "cycle," from Greek "kyklos," meaning "circle" or "wheel." Its making follows the pattern of "bicycle" and "tricycle," which name vehicles by their number of wheels, so the word simply announces how many wheels the machine has. The Latin prefix and the Greek root were brought together in a modern coinage, a reminder that English often builds new terms from classical building blocks as needed. The "cycle" element itself was in use for vehicles long before the four-wheeled version appeared, which is why the word reads so transparently: a reader who knows "bicycle" can work out its meaning at once.

Synonyms: four-wheeler
