SO

ara(i)

meaning: coarse, rough

Left radical is 'rice' (米). Right radical is 'furthermore' (且), which acts here phonetically to express 'neglect'. This character originally referred to spilled/neglected rice; it came to mean poor quality things in general, and things that are crude or rough metaphorically as well. Henshall suggests as a mnemonic: 'Furthermore, rice is coarse.'
