What does bumpy mean?
Bumpy is an adjective describing something covered with bumps or otherwise rough and uneven — a potholed road, a corrugated track, or a jarring flight through turbulence. It derives from the noun bump, which likely arose as an imitative or expressive word for a sudden blow or swelling. Beyond its literal sense, bumpy is widely used figuratively to describe experiences marked by ups and downs: a bumpy launch, a bumpy economy, a bumpy friendship. In this extended use it suggests intermittent trouble rather than outright failure — the journey continues, but not smoothly. The word is common in both British and American English, informal to neutral in tone, and appears frequently in journalism, especially phrases like 'a bumpy road ahead'. Its comparative and superlative forms are bumpier and bumpiest, its adverb is bumpily, and its abstract noun is bumpiness. Related descriptive words include lumpy, jumpy, grumpy, and stumpy, all sharing the same -y suffix pattern.

(Figurative) Full of difficulties, fluctuations, or setbacks.

A 'bumpy ride' has been the go-to metaphor for political and economic turbulence for decades — pilots literally borrowed it from passengers.

Etymology of bumpy
Bumpy is formed from the noun bump plus the adjectival suffix -y, and dates from around the late 18th century. The noun bump itself emerged in the 16th–17th century, probably as an imitative or expressive formation suggesting a blunt blow or swelling, though its deeper origin is uncertain. It is related in form to words like plump and bumpkin, but no classical Latin or Greek root is involved, so it lacks true cognates in the Romance-language sense. The figurative use describing difficult journeys or processes developed naturally from the literal one.
