Bissau is the capital city of Guinea-Bissau, a small country on the west coast of Africa. It is a port, so ships use it. The country name itself contains Bissau, which can confuse people: Guinea-Bissau is the country; Bissau is the city. There are several countries with “Guinea” in the name, and they are not the same place. Write it with a capital letter; it is a place name.
