The word 多亏 is formed through a vivid conceptual blend of its two component characters: 多 (duō), meaning "many" or "much", and 亏 (kuī), which carries the core idea of a "deficit", "shortcoming", or "loss". When combined, they create a metaphor where one mentally tallies up a multitude of deficits or things that would have gone wrong, a scenario of "many losses". However, the word's actual meaning flips this into a positive expression, essentially implying "in spite of what should have been many losses, there was a gain or rescue". Thus, the formation embodies a recognition of averted negative outcomes, evolving into a term used to express gratitude or relief for a fortunate turn of events that overcame a potential multitude of shortcomings.
