hindsight
UK: ˈhaɪndsaɪt | US: ˈhaɪndsaɪt
n. understanding or judgment of an event or situation after it has occurred
n. the ability to see clearly what should have been done in a past situation
The word hindsight emerged in the early 19th century, combining hind (referring to looking backward) and sight (the act of seeing). It metaphorically describes the clarity one gains about past events—like "looking back" with improved understanding. The term reflects a universal human experience: realizing what should have been done only after the fact.
