Sand in Chinese / Japanese...

沙 means sand in Chinese, Japanese Kanji, and old Korean Hanja.

This can imply something infinite like the sands of the Ganges. It's often used in Buddhism to suggest something countless.

This can also be the Japanese female given name Migiwa, so it’s kind of like the English name Sandy.

砂 means sand or gravel in Chinese, Japanese Kanji, and old Korean Hanja.

The radicals in the character imply the grit from ground-down stone or rock.

This can also be the Japanese surname Sunahama.

This Japanese Kanji means pear.

This refers specifically to the Pyrus pyrifolia and more specifically the culta variety. This is also known as the Japanese pear, Asian pear, sand pear, or apple pear.

梨 is also a female given name or surname in Japan that beyond Nashi, can be romanized as Rin, Rika, Ri, Nashisaki, or Shina.

In Chinese, this is pronounced like lee or li and just means pear.
