Word History

Etymology

Verb (1)

borrowed from Middle French fuser "to cause to melt," verb derivative from Medieval Latin fūsus, past participle of fundere "to cast (metal), melt down, make liquid," going back to Latin, "to pour, shed, cast (liquid metal)" — more at found entry 5

Note: Though "to melt, make liquid" is a primary sense of Medieval Latin fundere (and its Romance progeny, as French fondre), this meaning is only marginally attested in Classical Latin and may have originally been a technical sense used by metalworkers.

Noun (1)

derivative of fuse entry 1

Noun (2)

probably shortening of fusee in sense "fuse"

Note: The hypothesis that the word was borrowed from Italian fuso "spindle" appears to be without foundation. There is no evidence for the use of fuso in Italian in the sense "train of combustible material," the corresponding word being spoletta; note that spoletta in Tomaso Moretti's Trattato dell'Artiglieria (Venice, 1665) is rendered indiscriminately as both fuse and fusee in the English translation by Jonas Moore (A General Treatise of Artillery, London, 1683).

Verb (2)

derivative of fuse entry 2 or fuse entry 3
