🎤Pronunciation
🌳Etymology
Origin
Surface derives from Latin superficies, combining super (above) and facies (face/appearance), originally meaning the upper boundary or outer face of an object. Runoff is a compound of the verb run (to move rapidly) and the adverb off (away), describing water flowing away from a surface, particularly in hydrology.
Breakdown
Surface: super- (above) + -ficies (face/appearance, from Latin facies). Runoff: run (move rapidly) + off (away/separate), a phrasal verb construction describing water movement across terrain.
