means The achievement of a goal, aim, or desired outcome — getting the thing you set out to get.

from From Latin successus, the noun form of succedere, 'to come up, follow after, go well.' Break it down: sub- ('under, up from below') plus cedere ('to go, move'). So at its root, success literally means 'a coming-up' or 'a following-after' — the next thing that happens. Tellingly, early English use could mean any result, good OR bad (you could have 'good success' or 'ill success'); only later did the word quietly assume that the outcome must be a happy one. The same cedere gives us 'proceed,' 'succeed,' and 'cede.'
