Etymology
Origin of intervene
First recorded in 1580–90; from Latin intervenīre “to come between,” from inter- inter- + venīre “to come”; see also basis, come
Explanation
From the Latin "intervenire," meaning “to come between,” the verb intervene means just that: to get involved, to jump in the middle of something, to interfere. The verb intervene was first recorded around 1600. Since then there haven't been many interventions in its meaning or usage. You should probably intervene in a heated verbal fight between two of your friends before it escalates and gets physical. Especially if they're debating the United States’ habit of intervening in international conflicts.
