About
The character "雷" derives from an early representation of thunder, constructed from the semantic component "雨" meaning rain and the element "田", which likely served to suggest the recurring rumble associated with a storm. This structural arrangement has persisted in the traditional form of the character, which remains identical in its simplified version. While its core definition has always centered on the audible manifestation of atmospheric electricity, the term has experienced a semantic expansion, now commonly applied metaphorically to describe ideas or situations that deliver a sudden, unsettling surprise, marking a transition from a specific natural phenomenon to a broader figurative expression.
