🎤Pronunciation
🌳Etymology
Origin
Originally an architectural term in English, referring to the practice of inserting new supporting structures (pins or props) beneath weakened foundations of old buildings to reinforce them. The meaning later extended metaphorically to signify 'to provide a basis or foundation for' in abstract contexts, such as supporting theories or arguments.
Breakdown
under- (beneath, below) + pin (to fasten or secure with a pin-like prop). The compound literally means to support or secure from below, then developed abstract sense of providing foundational support.
