Bento
Box Lunch
noun
You know how 弁 means dialect and 当 means success? Well, this isn't going to help you much, because this means bento or box lunch. Chances are, though, you know the word "bento" from English. So, if you read this word (which you should be able to) you can figure out it's べんとう. If you do that, you can realize this word means bento too!
べんとう
This is a jukugo word, which usually means on'yomi readings from the kanji. If you know the readings of your kanji you'll know how to read this as well.
私のかばんの中には、さいふと、弁当と、タバコが一箱入っています。
In my bag, there's a wallet, a bento, and a pack of cigarettes.
お弁当のおかずを少し残しておいて、子猫にあげました。
I left some sides in my box lunch and gave them to a kitten.
明日あなたにお弁当作ってあげようと思うんだけど、何か苦手なものとかあるの？
I think I’ll make a bento box for you tomorrow. Is there anything you’d prefer not to have?
