Etymology

edit
 
A ladder leading to the vaults under the pedestal of the former National Kaiser Wilhelm Monument in Berlin, Germany. The word echelon is derived from French and Latin words meaning “ladder”.

Borrowed from French échelon (“rung; echelon”), from échelle (“ladder”) + -on (diminutive suffix). Échelle is derived from Latin scāla (“ladder”), from scandō (“to ascend, climb”), from Proto-Indo-European *skend- (“to jump”).
