Lime is a term that holds significance in various contexts, from culinary uses to chemical applications. Often misunderstood or underappreciated, lime can refer to both a fruit (the citrus variety) and a mineral (calcium oxide). In this article, we will explore the definition of lime, its types, applications, and interesting facts that highlight its importance.
