patent, clear
彰 centers on making something clearly visible or publicly recognized: a patent is an official public declaration, and clear means evident or manifest.
彰 combines 章 (a clear pattern or emblem) with 彡 (fine lines or decoration), suggesting making a pattern distinct or manifest. The exact historical development is uncertain, but the component combination fits the meaning of making something clear or patent.
章 is a clear emblem or badge, and 彡 adds decorative lines that make it stand out. Together, 彰 means making something patent and clear, like a badge displayed prominently.
For ショウ, imagine a patent officer named Show who stamps documents to make them official: Show -> ショウ, and the stamp makes the patent clear.
