found: Aside from the past form of find, there are two distinct words found in English. Found ‘establish’ [13] comes via Old French fonder from Latin fundāre, a derivative of fundus ‘bottom’ (which, like English bottom, goes back ultimately to Indo-European *bhud- or *bhund-). The Latin words also gave English founder, fund and fundamental. Found ‘melt’ [14], which is now mainly represented by the derived foundry [17], comes via Old French fondre from Latin fundere ‘pour, melt’.

This goes back to Indo-European *ghud-, *gheud-, from which English also gets ingot. Amongst related forms in English are (from French fondre) font, fondant, and fondu, (from Latin fundere) funnel, (from the Latin past participle fūsus) fuse and fusion, and (from *fud-, the immediate root of Latin fundere) futile [16], which etymologically means ‘that pours away’, hence ‘useless’.
