にし
- flat (heiban)
How to read it: a line over a kana means the voice is high there, and ↓ marks where it drops. A kana with no line is low. With no ↓ the pitch stays high to the end and does not drop even on a following particle (が, は).
west
Nishi may originally be 去に (ini, “going away”) plus し (shi, “wind; (by extension) direction”).

- “Originally a compound of 去に (ini, “going away”, the 連(れん)用(よう)形(けい) (ren'yōkei, “stem or continuative form”) of the verb 去(い)ぬ (inu, “to go away”)) + し (shi, “wind; (by extension) direction”, as seen in other ancient-derived words as 嵐 (arashi, “storm”, literally “wild + wind”), 旋風 (tsumuji, “whirlwind”), 東 (higashi, “east”, from older pi muka si, literally “sun + facing + wind/direction”)).”
- “First cited in the Kojiki of 712, with the phonetic spelling 爾斯 (nisi).”
