**Marlinespike** → The word is formed from "marline" (a type of small rope used in sailing, derived from the Old English *mearc*, meaning boundary or mark) and "spike" (from Old English *spica*, meaning a pointed tool). The term "marlinespike" refers to a pointed tool used in rigging to separate strands of rope or to help in knot tying.
Think of a 'small rope' ('marline') and a 'pointed tool' ('spike') that helps sailors with their ropes and knots.
