Meaning
The kanji 砂 (suna, SA) means "sand," a common granular material found widely in nature. It's formed as a phono-semantic compound (形声文字 - keisei moji), a common way to create kanji where one part suggests the meaning and another hints at the pronunciation. On the left, you'll find the radical 石 (ishi), meaning "stone" or "rock." This radical is the semantic component, clearly showing that 砂 relates to stone. This makes sense because sand consists of tiny fragments of rock, minerals, and organic matter. These materials break down over time due to weathering and erosion.
The right-hand component is 少 (shou), meaning "few," "little," or "small." While 少 provides a phonetic hint, especially from older Chinese pronunciations, its visual presence also reinforces the meaning. It evokes the countless "small" particles that make up sand, emphasizing its granular nature. So, 砂 can be visually interpreted as "small stones" or "finely divided stone." This perfectly captures the essence of sand: pulverized rock.
With 9 strokes, 砂 is a Kyōiku Kanji, taught in the 6th grade of Japanese elementary schools. It's also an N3 level kanji in the JLPT. This means it's important for Japanese learners and frequently appears in everyday vocabulary. Understanding how it combines "stone" and "small" helps learners memorize it, directly linking its visual form to its meaning.
Readings
The kanji 砂 has both On'yomi (Chinese-derived) and Kun'yomi (native Japanese) readings, which are used in different contexts. For intermediate learners, mastering these readings and their vocabulary is crucial for understanding Japanese texts and conversations.
On'yomi (音読み) — Chinese-derived readings
