Etymology

spoon (n.)

O.E. spon "chip, shaving," from P.Gmc. *spænuz (cf. O.N. spann, sponn "chip, splinter," Swedish spån "a wooden spoon," O.Fris. spon, M.Du. spaen, Du. spaan, O.H.G. span, Ger. Span "chip, splinter"), from PIE *spe- "long, flat piece of wood" (cf. Gk. sphen "wedge"). 

The meaning "eating utensil" is c.1300 in English (in Old English such a thing might be a metesticca), probably from O.N. sponn, which meant "spoon" as well as "chip, tile" (development of the "eating utensil" sense is specific to Middle English and Scandinavian, though M.L.G. spon also meant "wooden spatula"). Spoon-feed is from 1610s; figurative sense is attested by 1864. To be born with a silver spoon in one's mouth is from 1801.
