To Make Someone Wait
To Keep Someone Waiting
transitive verb, ichidan verb
This word consists of kanji with hiragana attached. Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means wait so this word has something to do with waiting. Use the たせ as a hint. Someone "tossed" a ball off into a ditch, and then they had to find it. They made you wait for them to get the ball too, even though it's a cheap piece of crap. Feel upset about this. That'll help you remember that this means to make someone wait and to keep someone waiting.
