Appropriationist is a term used to refer to someone who takes something without permission or the act of taking something that belongs to someone else for your own use. However, there are several synonyms for this word, such as usurper, thief, stealer, robber, looter, or plunderer. Each of these words highlights the fact that the act of appropriationist is an unlawful or unethical act. Some synonyms denote more specific types of appropriation, such as embezzler or pilferer, which suggest the stealing of money or property on a small scale. Regardless of the specific word used, they all point to the same thing: an individual taking something that is not rightfully theirs.
