Transitive VerbIntransitive VerbAdjective

When used as a verb, the word suggests a gradual, natural expansion. It evokes the image of a drop of ink spreading through a glass of water or a secret slowly leaking through a community. It carries a neutral to positive connotation of distribution and accessibility.

As an adjective, the term shifts toward a critique of clarity. In a linguistic sense, it describes a style that wanders or rambles, often implying a lack of discipline in thought. In a physical sense, it describes a softening effect, such as light passing through a curtain, which removes sharp edges and creates a muted atmosphere.
