IPA: /ˈtɜrnˌpaɪk/
KK: /ˈtɜrnˌpaɪk/
A type of road where drivers must pay a fee to use it, often found in the form of expressways with toll booths.
We took the turnpike to avoid traffic on the local roads.
Turnpike → The word is formed from "turn" (from Old English "turnian", meaning to rotate or change direction) and "pike" (from Old French "pike", meaning a pointed stake or pole). A turnpike originally referred to a road where a barrier (or pike) was turned to allow passage, often requiring a toll to be paid.
Imagine a road where you have to 'turn' to get through a 'barrier' or 'stake' — that's how a turnpike works.
