What does cleanup mean?
A "cleanup" is the act or process of making something clean, orderly, or free of unwanted matter — whether that means clearing debris from a beach, tidying a room, or removing toxic waste from a contaminated site. The word also carries a strong figurative sense: a "cleanup" of an institution or industry describes a determined effort to eliminate corruption, fraud, or misconduct, giving the term a connotation of reform and renewal. In American sports, it has a further specialized life: the "cleanup" spot in a baseball batting order belongs to the hitter expected to drive base runners home. Written as a single word when used as a noun, cleanup pairs naturally with terms like "effort," "operation," and "crew." Its everyday familiarity makes it useful across registers, appearing everywhere from environmental policy reports to household conversation, always suggesting the satisfying transformation of disorder into order.

Etymology of cleanup
The noun "cleanup" is formed by compounding the native English adjective/verb "clean," which derives from Old English "clǣne," with the adverbial particle "up." Such verb-plus-particle conversions into nouns became widespread in modern English, especially in American usage. It shares its root with related forms such as "cleanse," "cleanly," and "cleanliness," all tracing back through Old English and Proto-Germanic origins rather than Latin or Greek borrowing.
How cleanup is actually used
Standard in both British and American English, though the baseball sense is largely American. As a noun it is written as one word; the related verb phrase remains two words.
