Definition
Meaning
A fast, energetic dance popular in the 1930s and 1940s, performed to swing music.
Informally, someone who dances wildly or energetically; also used in computing/electronics to describe small, rapid fluctuations or instability in a signal or system.
Linguistics
Semantic Notes
The primary meaning is historical/dance-related. The computing sense is a metaphorical extension based on rapid, uncontrolled movement. The word carries nostalgic or period-specific connotations in its main sense.
Dialectal Variation
British vs American Usage
Differences
The dance sense is equally understood in both variants, associated with American cultural history. The computing/electronics sense is more international technical jargon.
Connotations
In both BrE and AmE, the dance sense evokes the swing era. It may be slightly more familiar in AmE due to its American origins. The computing sense is neutral technical terminology.
Frequency
Very low frequency in general modern usage. The dance sense is encountered in historical contexts; the technical sense appears in specialized fields.
