This word is from the Spanish barricada.
barikada
barricade
nakabarikada
to have a barricade in place
nakabarikada
to be barricaded in
A barricade is an object or group of objects that creates a barrier or obstacle that prevents the passage of people or things.
To barricade oneself is to shut oneself in a position by having a barrier against external forces.
Tatlong araw nang nakabarikada ang mga sundalo sa loob ng gusali.
The soldiers have barricaded themselves inside the building for three days now.
* Not to be confused with barkada (meaning: peer group).
KAHULUGAN SA TAGALOG
barikáda: pansamantalang harang o bakod na itinayo para hindi makapasok ang tao, hayop, at sasakyan
I believe that the word barkada which means peers aptly originated from barikada meaning barricade rather than from barcada which means shipload. It’s probably an offshoot of the word “kabarikada” meaning from the same protecttive barrier and later became kabarkada.
