Dao is by no means the only character with such different meanings, although it is a special case. De, 德, has the same multiplicity of them: “virtue”, “power”, “excellence”, “force”, “conduct”, “charisma”. And so do many other graphs of philosophical import. At the same time, many other graphs do not have meanings different enough to cause philosophical problems of interpretation.  Fa, 法, entries, for example, include “law”, “regulation”, “method”, “pattern”, where the general meaning of fa is fairly clear, or at least clear enough that any of the English terms could normally be used to translate it without undue loss of meaning, or philosophical distortion.
