Cognate with Old High German rocco, rocko, roccho, rocho ("a distaff"; > German Rocken (“a distaff”)), Swedish rock (“a distaff”), Icelandic rokkur (“a distaff”), Middle English rocke (“a distaff”). More at rock⁴. For the meaning development, compare fuselage, ultimately from Latin fūsus (“spindle, spinning wheel”).
