noun
saddle flap
A leather or cloth flap attached to a horse's saddle to protect the rider's legs from mud. This is a specialized equestrian term; the reading あおり is a gikun (meaning-based reading) for the kanji 障泥.
馬に乗るときは、障泥を付けて泥はねを防ぐ。
When riding a horse, attach the saddle flap to prevent mud splashes.
Sino-Japanese reading (on'yomi) of the same kanji; rarely used in modern Japanese.
Alternate kanji order; less common than 障泥.
The kanji 障 (obstruct) and 泥 (mud) literally mean 'mud guard'. The reading あおり is a gikun (meaning-based reading) applied to this compound.
