A hawker is a vendor of merchandise that can be easily transported; the term is roughly synonymous with costermonger or peddler. In most places where the term is used, a hawker sells inexpensive goods, handicrafts, or food items. Whether stationary or mobile, hawkers often advertise by loud street cries or chants, and conduct banter with customers, to attract attention and enhance sales.
