USAGE NOTE The expressions same and the same are sometimes used in place of pronouns such as it or one, as in When you have filled out the form, please remit same to this office. As this example suggests, the usage is associated chiefly with business and legal language, and some critics have suggested that it should be reserved for such contexts. But though the usage often does sound stilted, it occurs with some frequency in informal writing, particularly in the phrase lack of same, as in It is a question of money, or lack of same.
