‘Flutter/Stream’. Used to modify kurokami ‘black hair’, kusa ‘grass’, paru ‘spring’, etc. From the way that hair or blades of grass flutter in the breeze.
‘Good blue-black clay’. Used to modify Nara ‘Nara’, kunuti ‘within the land’. It appears from the Man’yôshû that Nara produced awoni clay used as a pigment, but whether this was really the case or simply a tradition is unknown.
‘Catalpa bow’. Used to modify piku ‘pull’, iru ‘shoot’, moto ‘base’, suwe ‘end/tip’, turu ‘bowstring’, yoru ‘draw near’, ya ‘arrow’, oto ‘sound’, kaperu ‘return’, etc. There is, in fact, some disagreement among the commentators as to whether adusa is catalpa or not.
