壁に星型のシールを貼った。
I put star-shaped stickers on the wall.
star polygon; stellated polygon
regular star polygon; stellated regular polygon
Standard kanji spelling for star-shaped objects or patterns.
Alternate kanji spelling; 形 emphasizes the shape itself.
Compound of 星 (hoshi, 'star') + 型 (kata, 'shape, mold'). The reading hoshi becomes hoshi- in compounds.
