A safety device containing a wire that melts to break an electrical circuit; also a cord that ignites explosives
From Latin fusus, past participle of fundere meaning to melt or pour
A fuse literally 'melts' to protect you - when too much electricity flows through, the metal wire inside gets so hot it liquefies and breaks the circuit. It's a tiny hero that dies to save your house!
