🚧 栏 = 木 wood radical + 兰 (lán) for sound = a wooden railing or fence
The 木 (wood) on the left tells you the material; 兰 (lán, orchid) on the right just lends the sound. Same lán also covers a column or box of text, like a fenced-off section on a page.
栏 — wood radical 木 + 兰 (lán, phonetic)
A semantic-phonetic compound: 木 ('wood') signals the meaning, while 兰 (lán) supplies the sound. Originally written 欄 in traditional form, it referred to wooden railings or fences, and by extension came to mean a column or bordered section, as in a newspaper column.
