IPA: /ˈpæθˌfaɪndər/
KK: /ˈpæθˌfaɪndər/
A person or thing that finds a new way or route, especially in unexplored areas.
The pathfinder led the team through the dense forest to find a safe passage.
Pathfinder → It is formed from "path" (from Old English *pæth*, meaning a way or track) and "finder" (from Old English *findan*, meaning to discover or locate). The word "pathfinder" refers to someone who discovers or creates a way or route.
Imagine someone who 'discovers' ('findan') a 'way' ('path') — that's why a pathfinder is someone who finds a way.
