StructureHow the kanji is literally written.
Two trees side by side suggest a little woodland! The kanji is literally written with two 木.
Repeating a component is a traditional way of suggesting “many” or “a group”. It is how these particular kanji are built, not a rule that adding meanings explains every kanji.
