The word "幸好" is formed through a conceptual combination where the first character, 幸 (xìng), conveys the core idea of "fortunately" or "by luck", establishing a scenario of accidental good fortune. The second character, 好 (hǎo), meaning "good", is appended not to create a simple sum but to intensify and positively evaluate that fortunate circumstance. Together, they merge into a single concept that expresses a sense of relieved gratitude, the recognition that within an otherwise potentially negative situation, a specific lucky or good element has favorably altered the outcome.
