GAIN, the profit or lucre a person reaps from his trade, employment, or industry. Some derive the word from the German gewin: whereof the Italians had made guadagno; the French and English gain.
There are legal and reputable gains, as well as sordid and infamous ones. What is gained by gaming is of the latter description. Such gains are not acknowledged by law, so that the payment is not legally binding on the loser.
