KK: /bærɪˈkeɪdɪd/
Blocked or protected by a barrier, often to prevent entry or to defend a position.
The entrance was barricadoed to keep intruders out.
Barricadoed is derived from "barricade" (from French *barriquer*, meaning to block or fortify) and the suffix "-ed" (indicating a past action). The term "barricadoed" refers to something that has been blocked or fortified with a barricade.
Think of a barricade as something that 'blocks' or 'fortifies' an area, and when something is 'barricadoed', it means it has been made secure or blocked off.
