The kanji 禁 is a phono-semantic compound (形声文字). The left side is a part of the character, 示 (示), which means "to show" or "altar" often relating to things associated with rituals or the divine, thus implying rules or commandments. The right side is 林 (hayashi), which means "woods" or "forest". The association here is that rules and laws are set forth within the forest, like a place that has restrictions. Therefore, 禁 combines the idea of rules and the environment in which those rules are imposed. Over time, the character evolved to more directly represent the concept of prohibition.
