IPA: /ˈoʊdəˌɡræf/
KK: /ˈoʊdəˌgræf/
A device used to measure and record the distance and direction traveled by a vehicle.
The odograph helped the driver keep track of the distance covered during the trip.
Odograph → It is formed from "odo-" (from Greek "hodos", meaning way or path) and "graph" (from Greek "grapho", meaning to write or record). The word "odograph" refers to a device or instrument that records the path or way traveled.
Think of 'odo-' as relating to a 'path' and 'graph' as 'writing' — so an odograph is a tool that 'writes' down the 'path' you take.
