empacar
/empaˈkaɾ/ · B1 · verb
to pack, pack away, pack up
📦🧳 em + paca (bale) + -ar = put into a bale; the PAC in empacar is English pack
Paca is Spanish for a bale or bundle, so empacar is to put things into a bale, which means to pack. The less common sense, to anger, works like English getting packed full of fury.
