About
杆 is a phono-semantic compound with the semantic radical 木 (wood/tree) on the left, indicating its material, and the phonetic component 干 on the right. The character originally denoted a solid wooden pole or rod used for practical purposes. Depending on its tone, it functions as a noun for a pole or lever, or as a measure word for long, cylindrical objects like rifles or pens. The component 干, which can mean "shield", "to interfere", or "dry", serves here solely for its phonetic value to indicate the character's pronunciation.
