Etymology
The word 'whiplash' is a transparent compound formed from two English words of Germanic and imitative lineage. 'whip', an instrument for striking, combines with 'lash', describing the act of striking with a flexible object. The term originally and literally referred to the stroke or crack of a whip. Its medical sense, describing a neck injury resembling the sudden snap of a whip, is a modern metaphorical extension from the early 20th century, illustrating how a vivid physical action provides a model for a specific bodily trauma.
Analysis
'whip' is from middle english 'whippen', of uncertain origin, possibly from middle low german or dutch, functioning as the object or instrument. 'lash' is from middle english 'lasshen', meaning to strike violently, likely of imitative origin, functioning as the action or result.
