帆
fān · HSK 7
to gallop; variant of 帆[fan1]
⛵ 巾 (cloth) + 凡 (common) = a common cloth catches wind — a sail
The left radical 巾 means cloth or towel, and 凡 on the right gives the sound fán. A sail is literally a piece of cloth rigged to catch wind. Note: this character primarily means sail, but has a rare variant reading meaning to gallop.
帆 — cloth radical 巾 + 凡 (phonetic)
帆 is a semantic-phonetic compound. The cloth radical 巾 on the left signals the meaning—a piece of fabric—while 凡 on the right gives the sound 'fan'. Together they denote a sail, the cloth that catches wind to propel a boat.
