🍀 幸 luck + 亏 loss/deficit = luckily you were spared the loss
幸 carries the sense of good fortune (as in 幸福, happiness); 亏 means a deficit or coming up short (as in 亏损, a loss). Together they flag relief that luck stepped in before a bad outcome — hence fortunately, luckily.
亏 — top stroke 一 + 丂 (hooked breath)
亏 is the simplified form of 虧. Originally 丂 depicted breath or air being exhaled with difficulty, suggesting something lacking or deficient. Over time it came to mean 'lose,' 'deficit,' or 'owe,' as in being short of what is needed.
