# estop

> English word · Verb · IPA /ɪˈstɒp/

## Definitions
1. To impede or bar by estoppel.
2. To stop up; to plug.

## Etymology
Uncertain. Traditionally derived from the rare Late Middle English estoppen (“to prevent conception”), from Anglo-Norman and Old French estoper, from a Late Latin stuppō. However, the modern senses appear rather to align more with the much commoner Middle English istoppen (“to block, obstruct, stop up, clog”), from Middle English i- (perfective prefix) + stoppen (“to block, stop”). More at stop.
