Amulet, Label, Playing Card
This word is almost the same as the kanji, but only half of it. It means tag or amulet. They're about the same shape and size as money, but you can't buy a house with them (...probably).
Since this word is made up of a single kanji, it should use the kun'yomi reading. When learning the kanji, you didn't learn that reading, so here's a mnemonic to help you with this word:
You can't find your tag anywhere. It was just there, you swear, but now it's nowhere to be found. You search for it everywhere, then you realize... it was right there all along. Seriously? You're such a fool, duh (ふだ)!
There were many amulets at the entrance of the village.
You should be careful not to show your hand.
I didn't knock because the vacant room tag was hung.
