Definitions for "Intangible"
Not tangible; incapable of being touched; not perceptible to the touch; impalpable; imperceptible.
Property or belongings which cannot be touched or seen, but which have value e.g. goodwill in a business.
Something that cannot be perceived by the senses. Accountants and financial types only grudgingly concede that some intangibles have value, and they find it in things like brand names and patents. Because you can't immediately sense a person's capability, a customer's loyalty, or a relationship with a supplier, accountants say these things have to value.
