Model
Noun and の adjective
げんけい
私たちはまず初めに、粘土で彫刻の原型を作るんです。
We usually sculpt a model out of clay at first.
The original model of something isn't usually very good. It's rough. It's a prototype.
This is a jukugo word, which usually means on'yomi readings from the kanji. If you know the readings of your kanji you'll know how to read this as well.
