Oplan. noun. A term coined from the Filipino word plano (or “plan” in English). Funny, because I always knew the meaning of this word ever since I was in grade school, not because it was obvious, but because it has been always associated in events such as oplan kapit-bisig, oplan tuli, oplan linis-kapaligiran, etc. Maybe when someone asked me that time why it was called oplan, I wouldn’t know exactly what to say.

Amazing how one unknown word becomes so familiar just because it’s been associated with something else so many times.
