Ate literally means "liver". It is the middle part of a Maori taiaha, a kind of two-handed war club. The ate serves as the grip. It can also be called tinana, meaning "body". 1
Glossary of taiaha parts
1. Upoko, head
2. Arero, tongue end
3. Tinana, body providing the grip (also called ate, meaning "liver")
4. Rau, flat smooth blade
Sometimes the upoko is adorned with a tauri (collar) of feathers and/or aice (tassels) of dog hair.
"About four inches of the shaft, close up to the carved part, is covered by a little tightly-fitting mat (tauri), made of flax into which are worked the bright scarlet feathers from under the wing of the large New Zealand parrot (Nestor), and at the lower edge of this are fastened a number of little quillets, or tassels (aice), of doghair, each quillet being elaborately bound up at the base with a kind of swordstitch, with a fine cord made of the best picked flax fibre. These tassels of hair form a handsome fringe about five or six inches long, and, being generally white in colour, contrast well with the brilliant red of the feathers, and the rich brown polish of the taiaha." 2
