🎤Pronunciation
🌳Etymology
Origin
The phrase evolved from its literal physical meaning of spatial depth ('deep' + 'down') to a metaphorical psychological sense meaning 'in one's innermost being' or 'at heart'. Like hidden truths existing in ocean depths unseen on the surface, the expression came to denote genuine emotions and authentic feelings concealed beneath outward appearances.
Breakdown
deep (extending far below the surface) + down (toward a lower position) = combining to express depths of the mind or heart; the spatial compound underwent metaphorical extension to describe psychological or emotional profundity.
