IPA: /ˈhiːlpoʊst/
KK: /ˈhilˌpōst/

Heelpost → The word is formed from "heel" (from Old English "hæle", meaning the back part of the foot) and "post" (from Latin "postis", meaning a vertical support or pillar). A heelpost refers to a vertical support located at the back or heel area, often used in construction or carpentry.
Think of the 'back part of the foot' ('heel') being supported by a 'vertical pillar' ('post') — that's what a heelpost is.
