The word "decrease" comes from the Old French word "descroistre" which means "to decrease" or "to diminish". It is derived from the Latin word "decrescere" which has the same meaning. The term "by" comes from the Old English word "bi" which means "near" or "close to". Therefore, the phrase "decreases by" combines the Latin root for decrease with the Old English preposition "by" to indicate a reduction or diminishing in quantity or value.
