Terminal
Also called: End tile, 幺九, yaochuu
The 1 and 9 tiles in each numbered suit.
Terminals are the 1 and 9 tiles of each suit — six tiles total (1m, 9m, 1p, 9p, 1s, 9s). Together with the seven honor tiles, terminals form the 'outside' tile set used in patterns like Outside Hand, All Terminals, All Terminals and Honors, and Thirteen Orphans. The 'inside' tiles (2-8 of each suit) are called simples.
