"tool for digging," Old English spadu "spade," from Proto-Germanic *spadan (source also of Old Frisian spada "a spade," Middle Dutch spade "a sword," Old Saxon spado, Middle Low German spade, German Spaten), from PIE *spe-dh-(source also of Greek spathē "wooden blade, paddle"), which as a suffixed form has been grouped under a root *speh-, "with several extensions, denoting quite different implements" (Boutkan) but basically indicating "long, flat piece of wood" (source also of Old English spon "chip of wood, splinter," Old Norse spann "shingle, chip;" see spoon (n.)).
"A spade differs from a two-handed shovel chiefly in the form and thickness of the blade" [Century Dictionary]. To call a spade a spade "use blunt language, call things by right names" (1540s) translates a Greek proverb (known to Lucian), ten skaphen skaphen legein "to call a bowl a bowl," but Erasmus mistook Greek skaphē "trough, bowl" for a derivative of the stem of skaptein "to dig," and the mistake has stuck [see OED].
1871, a nonsense word coined by Edward Lear in "The Owl & the Pussy-Cat" (runcible spoon). The phrase runcible spoon has been used since 1926 for "spoon with three short tines like a fork," but OED writes that "the illustrations provided by himself for his books of verse give no warrant for this later interpretation."
As for Lear's inspiration for the word, suspicion falls on runcival, a contemporary variant of the old word rounceval "something big and loud," which is said to be from Roncevaux (French Rouncesvalles), the pass in the Pyrenees where Roland fell in battle.
kind of short, light, spoon-bladed oar, mid-14c., skulle, a word of unknown origin. The verb, "to propel with one oar worked from the stern," is by 1620s, from the noun. Related: Sculled; sculling.
1790, "cut short" (adj.), from cut (v.). Also used as a noun of a variety of things: a short spoon, a short tobacco pipe, a pop-gun, also a dismissive term for a naughty or wanton woman or girl. Also used of a wren or a hare.
