Having reached what was aimed at. Also having come after — the same word for achievement and for sequence.
Latin succedere (to come close after, to follow, to turn out well), from sub (close to) + cedere (to go, to yield); achieving an aim and simply coming after were never two separate meanings until English needed them to be.
Having reached what was aimed at, or having merely come after. The same word for achievement and for sequence, and only the sentence around it tells which.
