IPA: /ˈhoʊmˌbaʊnd/
KK: /hoʊmˈbaʊnd/
Someone who is unable to leave their home, often due to illness or disability.
After her surgery, she became homebound and needed help with daily tasks.
Homebound is formed from "home" (from Old English *ham*, meaning dwelling or residence) and "bound" (from Old English *bund*, meaning to be tied or confined). The word "homebound" describes someone who is confined to their home or unable to leave it.
Think of someone who is 'tied' ('bound') to their 'home' — that's why homebound means someone who cannot leave their home.
