IPA: /ˈlɪstəbl/
KK: /ˈlɪstəbl/
Able to be included in a list or to be enumerated.
The items on the agenda are listable for easy reference.
Listable → It is formed from "list" (from Old English *liste*, meaning a series or enumeration) and "-able" (meaning capable of). The word "listable" means capable of being listed or enumerated.
Think of a 'list' as a series of items that can be 'enumerated' or counted, and the '-able' means it can be done. So, something that is listable can be put into a list.
