What does busy mean?
"Busy" is one of the most frequently used adjectives in English, describing a person who is actively occupied with work or tasks and has little idle time. By extension it applies to places and periods characterized by heavy activity or traffic — a busy street, a busy season, a busy signal on a telephone line — and, less commonly, it functions as a verb meaning to keep oneself occupied. The word carries a double-edged connotation: industriousness and importance on one hand, stress and unavailability on the other, which is why "too busy" often signals neglect rather than diligence. Its derivatives are deeply embedded in everyday language, most notably "business," which originated simply as the noun form of being busy before evolving into its modern commercial sense. Derived from Old English "bisig," with a surviving Dutch cognate "bezig," it is among the oldest words in the language. Common idioms include "as busy as a bee" and "keeping someone busy," reflecting how central the concept of occupation remains to English-speaking life.
Actively engaged in work or activity; having a great deal to do. Of places, times, or things: marked by much activity, traffic, or use.
"The switchboard was busy all morning with calls about the sale."
For a telephone line, British English traditionally prefers "engaged" over "busy."
To keep oneself or someone else occupied with a task or activity, usually reflexively ("to busy oneself").
"She busied herself arranging flowers until the guests arrived."
Almost always used reflexively; the passive sense is rare. Somewhat formal in register.
"Busy" is one of the few common English words whose spelling gives no clue to its pronunciation — and it's the root of "business," which literally began as the state of being busy.

Etymology of busy
"Busy" descends from Old English "bisig," meaning diligently occupied, making it well over a thousand years old. Its closest surviving relative is the Dutch adjective "bezig," which shares the same Germanic root. From "bisig" came the Middle English noun "bisinesse," which developed into modern "business," originally meaning the state or quality of being busy. The spelling-pronunciation mismatch that makes "busy" look like it should rhyme with "musty" reflects sound changes after its spelling was fixed.

How busy is actually used
"Busy" is neutral to mildly positive when describing diligence, but can carry a negative connotation of being overwhelmed or unavailable; phrases like "too busy" often imply neglect. In British English a phone line described as "busy" is more usually called "engaged." The verbal use ("to busy oneself") is somewhat formal or literary compared with the dominant adjectival use.
