“Quadruplicated” means that something has been multiplied by four or has increased to four times its former amount, size, or value. It is the past tense and past participle of “quadruple” and can be used transitively, as in “the company quadrupled its output,” or intransitively, as in “sales quadrupled within two years.” The expression is formal but broadly understood and is especially common in business, science, finance, and statistics, where substantial increases are being described. It can also be used before a noun in a participial construction, such as “a quadrupled workload.” Although the shorter form “quadrupled” is more prevalent in contemporary prose, “quadruplicated” remains a standard grammatical form.
