Etymology
The term is a modern American English compound, originating in early 20th-century retail slang. It vividly literalizes a deceptive practice: first, the "bait" (an irresistible offer) is dangled to attract the customer, much like bait on a hook. The conjunction "and" simply links this action to the inevitable, dishonest follow-up: the "switch," where the promised item is replaced with an inferior or more expensive alternative. The logic is transparent and metaphorical, drawing from the concrete domains of fishing (bait) and mechanical substitution (switch) to create a powerful label for a specific form of fraud.
Analysis
Structure: bait (lure) + and (conjunction) + switch (substitute)
• bait: From Old Norse beita (food, to cause to bite). Functional role: The initial, attractive lure.
• and: From Old English and, ond (a particle expressing addition or connection). Functional role: A conjunction linking the two actions.
• switch: Likely from Middle Dutch swijch (a flexible twig). Functional role: The subsequent act of substitution or change.
