I’m looking for a heart shaped stone to use on my fake nails.
Kristen was swinging a heart shaped hammer around while holding nails in her mouth.
When flamingos kiss, their heads and necks form a heart shape.
ハート is of course "heart" and you know that 形 means shape. You've probably already figured this one out. It's heart shaped.
You can add this kanji to all sorts of other things too to say "____ shaped." Give it a try!
The reading for the kanji portion uses the kun'yomi reading. This is kind of like the reading you already learned for 形 just without the ち part. And rendaku happens too, so it becomes がた. If you can remember that, you should be able to remember this reading too!
