حصن

حِصَانٌ حصان A generous, or high-bred, horse, (Msb, K,) of whose seed one is niggardly: (K:) or a male horse: (Mgh, K:) or this latter is a secondary meaning, originating from frequency of usage: (S, Msb:) or a stallion horse; or one fit to cover: (TA voce رَاحَ:) the حِصَان is. so called because he preserves his rider: (TA:) or because his back is like the حِصْن to his rider; (Mgh, Msb;) wherefore horses are called حُصُونٌ: (Mgh:) or because one is niggardly of his seed, so that he is not made to cover any but a generous mare: (S, Mgh, Msb:) pl. حُصُنٌ. (Mgh, Msb, K.)
