Change refers to the process of becoming different. It commonly describes small denominations of money given in exchange for a larger denomination, a replacement, e.g. a change of clothes, and balance of money returned from the sum paid after deducting the price of a purchase, which gives the term a broader and more practical sense than a single short definition would suggest. Depending on context, it can also point to usually coins (as opposed to paper money), but sometimes inclusive of paper money, a transfer between vehicles, and a change-up pitch, so the category can cover literal uses, related ideas, and more figurative extensions of the same core meaning. Taken together, these meanings present Change as a flexible theme rather than a narrowly technical label, covering the central idea people usually mean when they use the word while still leaving room for closely related senses that appear in real language. Additional shades of meaning include a place where merchants and others meet to transact business; an exchange, a public house; an alehouse, to become something different, to make something into something else, and to replace, which reinforce how the category can stretch across adjacent but still recognizable uses of the same term.
