Luggage, Baggage, Load
noun
A luggage thing is your luggage. It's also your baggage and load too.
にもつ
This is a jukugo word, which usually means on'yomi readings from the kanji. You'll need to remember the 物 reading as もつ, though. Why? Because all your luggage just got thrown into various moats along the countryside. It's going to take you forever to collect your luggage from these moats and by then it'll be all soggy. Dangit...
