Tiles & Melds
Simple
Also called: Middle tile, 中張牌, chunchan
The 2-through-8 tiles in each numbered suit.
Simples are the middle-rank tiles in each numbered suit: 2, 3, 4, 5, 6, 7, and 8 of manzu, pinzu, and souzu. They're the opposite of terminals (1s and 9s) and honors (winds and dragons). The All Simples (Tanyao in Riichi, Duan Yao Jiu in MCR) pattern requires every tile in your hand to be a simple.
