What does insensibly mean?
Insensibly means that a change, movement, or effect cannot be perceived or noticed. It often describes something that happens so gradually that its effects become apparent only after they have been developing for some time: a shoreline may erode insensibly, or a preference may shift insensibly as experiences accumulate. The word can also describe conduct performed without awareness or sound judgment, although this sense is less common and more formal than the idea of imperceptible change. In careful usage, insensibly is distinguished from invisibly because it need not imply complete concealment; the emphasis may instead fall on the subtlety or gradual nature of something. The adverb is related to insensible and, through it, to the larger English sense-word family, including sensible, sensibility, and sensory.
