The term "particular purpose" refers to a specific goal or objective that something is intended for. It implies that whatever is being referred to has been designed, created, or used with a particular use in mind and not for general purposes. The phrase can be used to describe an item's function, a person's intention, or the reason behind someone's actions. In legal contexts, it often appears in contracts or warranties to indicate that something is being purchased or guaranteed for a specific purpose only, rather than for any and all purposes.
