Words have meaning, obviously. But how much meaning do they entail exactly? When someone says; I prefer direct communication. How direct? A little less indirect than very indirect? Adjectives aren’t all that helpful.
Describing personality traits and soft-skills, requires more than just words. It requires an added linguistic layer. An auxiliary semantical layer that provides a scale for words that are supposed to be clear. However, without a sense of gradation, the same word in the same language can mean something different altogether, depending on the interpretation.
