escalator

The story

1. Latin · derived fromē-“from, out of”
2. English todayescalator

By genericization from the former trademark Escalator, created by American inventor Charles Seeberger in 1900, from Latin ē- (“from, out of”) + scala (“ladder”) + -tor, which forms nouns of agency; see the appendix. Broader usage may be influenced by its derivative escalate, by surface analysis, escalate + -or. For an alternative etymology, see the Online Etymology Dictionary.
