IPA: /ˈʃiːpʃæŋk/
KK: /ˈʃipˌʃæŋk/
A type of knot used to shorten a rope or line without cutting it.
The sailor tied a sheepshank to secure the extra length of rope.
**Sheepshank** → The word is formed from "sheep" (from Old English *sceap*, meaning a domesticated animal raised for wool and meat) and "shank" (from Old English *sceanca*, meaning the lower part of the leg). A sheepshank is a knot used to shorten a rope, metaphorically relating to the idea of 'shortening' as one might shorten the leg of a sheep.
Think of a 'sheep' and a 'leg' ('shank') — a sheepshank is a knot that shortens something, just like how you might shorten the leg of a sheep.
