Unit-Pricing Word is a term used to describe the practice of pricing items individually, rather than in bulk. It is also known as 'price PER unit' or 'unit pricing'. The term is made up of three words: PER (3 letters), EACH (4 letters), and APIECE (6 letters). PER refers to the cost of EACH individual item, EACH indicates that the cost applies to EACH item, and APIECE is an informal way of saying 'EACH'. Together, these three words form the term Unit-Pricing Word, which is used to describe the practice of pricing items individually.
