IPA: /ˈboʊlˌtroʊp/
KK: /ˈboʊlˌtroʊp/
A strong rope that is sewn into the edge of a sail to make it stronger and prevent damage.
The sailor checked the boltrope to ensure it was secure before setting sail.
Boltrope is formed from "bolt" (from Old English *bolt*, meaning a strong, heavy object) and "rope" (from Old French *rope*, meaning a long, flexible material). The word refers to a strong rope used to secure or fasten something, particularly in nautical contexts.
Think of a 'strong object' ('bolt') that is 'secured' ('rope') — that's why a boltrope is a strong rope used for fastening.
