Bastardisation, also known as corruption, debasement, or contamination, is a term used to describe a process of altering something in a negative way- often resulting in an unfortunate outcome or loss of originality. Some other synonyms for "bastardisation" are defilement, adulteration, devaluation, erosion, tainting, and deterioration. These words can all describe situations where the original idea, concept, or product has been altered or changed so that it no longer reflects its original purpose, purity, or value. When creative works, cultural practices, or social constructs are "bastardised," it can lead to a loss of cultural identity, tradition, or moral values.
