軽い

Etymology
From, in turn from. In Old Japanese, seldom used outside of proper nouns, where in the ' it is spelled as 加流 and in the ' it is spelled as 軽, suggesting that this word was already used in Old Japanese with the meaning "light, lightweight". This might be weakly strengthened by a kana annotation of 軽 as karu(ku) in the .

It is generally believed that karu(si) was the older form; this is also supported by Ryukyuan cognates (see ). In the and, the variant  →  has started to be in use, while  →  has still seldom usage.

Later, both karosi and karusi began to be used in parallel. Then, in Early Modern Japanese, karui slowly began to replace karoi.
