A parasite-prone peacock, for example, is more likely to be discovered by a discerning peahen because parasite infestation demonstrates itself as damage to plumage (which is more noticeable given the peacock's bright coloration).
An appraisal is a judgment of something, especially an estimate of how much it's worth. Usually you need an expert to give an official appraisal. If you were selling a house, you'd need an expert in real estate to give an appraisal of how much it's worth â that's an official estimate of how much you could sell it for. But this word can also be used in other less formal situations that call for a judgment or opinion of some sort.
An appraisal report is a document that: 1  Clearly states the kind of value being determined, such as fair market (used for taxes), replacement (used for insurance coverage), liquidation (used for bankruptcy or business dissolution), etc.  Describes the property being valued.
