Who is Tanaka’s younger sister?
I feel betrayed by my little sister.
My younger sister just cut off all of her hair so she could make wigs for her Barbie dolls.
The kanji and the word are exactly the same. That means they share meanings as well.
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:
Your younger sister is really into emotes (いもうと). Look up this word if you're not a teenage girl. Just imagine her sending you these on your phone over and over. You tell your younger sister: "HEY, STOP SENDING ME EMOTES."
