Etymology
Origin of transition
First recorded in 1545–55; from Latin trānsitiōn-, stem of trānsitiō “passage, transit across,” from trānsit(us) “gone across” (past participle of trānsīre “to go across, pass over”; cf. transit ) + -iō -ion
Explanation
A transition is a change from one thing to the next, either in action or state of being—as in a job transition or as in the much more dramatic example of a caterpillar making a transition into a butterfly. Transition is awfully reassuring in its tidy reliance on regular forms. Trans means "cross," so when you hear it at the beginning of a word you know that it indicates crossing, as in transatlantic or translate. An odd thing happening with transition lately is that it is transitioning from its familiar form as a noun to a newer life as a verb, as in “We’re going to transition Gloria to that new job.”
