find: [OE] Find is a widespread Germanic verb, with relations in German (finden), Dutch (vinden), Swedish (finna), and Danish (finde). Further back in time, however, its ancestry is disputed. Some have connected it with various words for ‘path, way’ in Indo-European languages, such as Sanskrit panthās and Russian put’, and with related forms denoting ‘go, journey’, like Old Saxon fāthi ‘going’ and Old High German fendeo ‘walker’; others have suggested a link with Latin petere ‘seek’.
