The Spanish verb 'repasar' (meaning 'to review' or 'to go over again') comes from combining two elements: the Latin prefix 're-' meaning 'again' or 'back', and the Spanish verb 'pasar' meaning 'to pass'. The verb 'pasar' itself has an interesting etymology, tracing back through Vulgar Latin 'passare' ('to step, pass') to Latin 'passus' ('step'), which ultimately derives from the Latin verb 'pandere' meaning 'to stretch or extend'.

The semantic evolution from 'to stretch' to 'to review' is quite logical: imagine physically walking over the same path again (re-passing), which metaphorically became the act of mentally going over material again in review. The stretching meaning in 'pandere' evolved to represent the stretching of one's legs in taking steps ('passus'), which then generalized to the concept of passing or moving through ('pasar'), and finally with 're-', it became the act of passing over something again in review ('repasar').

The most obvious and common related Spanish word is 'pasar' (to pass, to go through), which is used very frequently in Spanish. You might already know phrases like 'ΒΏquΓ© pasa?' (what's happening?) or 'pasarlo bien' (to have a good time). Other related words include 'pasaje' (passage), 'paseo' (walk, stroll), and 'paso' (step). All these words share the basic concept of movement or passing through something.

English speakers can easily connect 'repasar' to several familiar English words that share the same Latin origins. The most obvious is 'pass' and its derivatives like 'passage', 'passing', and 'past'. The 're-' prefix is also very familiar in English, appearing in words like 'repeat', 'review', and 'return', all sharing the meaning of 'again' or 'back'. Understanding these connections can help remember that 'repasar' essentially means to 'pass over again' or 'review'.
