{{11}}shock (1) "sudden blow," 1560s, a military term, from M.Fr. choc "violent attack," from O.Fr. choquer "strike against," probably from Frankish, from a P.Gmc. imitative base (Cf. M.Du. schokken "to push, jolt," O.H.G. scoc "jolt, swing"). Meaning "a sudden and disturbing impression on the mind" is from 1705; medical sense is attested from 1804. The verb, "to come into violent contact" is attested from 1570s; meaning "to give (something) an electric shock" is from 1706; sense of "to offend, displease" is first recorded 1690s. Shock-absorber is attested from 1906; shock wave is from 1907. Shocking pink introduced Feb. 1937 by Italian-born fashion designer Elsa Schiaparelli. Shocker "something that shocks or excites" is from 1824. Shock troops (1917) translates Ger. stoßtruppen and preserves the word's original military sense.

{{12}}shock (2) "bundle of grain," early 14c., from M.L.G. schok "shock of corn," originally "group of sixty," from P.Gmc. *skukka- (Cf. O.S. skok, Du. schok "sixty pieces," Ger. Hocke "heap of sheaves").

{{12}}shock (3) "thick mass of hair," 1819, from earlier shock (adj.) "having thick hair" (1680s), and a noun sense of "lap dog having long, shaggy hair" (1630s), from shough (1590s), the name for this type of dog, which was said to have been brought originally from Iceland; the word is perhaps from SHOCK (Cf. shock) (2), or from an O.N. variant of SHAG (Cf. shag).
