Verbal contexts contribute to the interpretation of a word by helping to select the applicable sense or use. Some contexts are deemed diagnostic, in this regard, while others are relatively less helpful. I call them »indifferent«, such as colors and shapes for names of objects, since all objects have a color and a shape. Rare or less common words have a similar effect: »pellucid« in »a pellucid writing style«, for instance. If the contextual term or co-occurrent is itself polysemous, the larger context is required. For example, »pellucid« means both »easy to understand« and »lucid«, which cannot be applied simultaneously.
