Formal
Use of titles.
Ghanaians typically prefer a more formal communication style outside of the family and in the early stages of relationships. It is important to relate to people in a way that conveys respect for differences in hierarchical status.
Word choice.
There is sensitivity to the use of appropriate language, even in a more informal setting; words intended in jest such as "silly" or "stupid" may cause offense, and although some people may use profanity or obscenity, it is generally considered inappropriate in the workplace.
Personal
Ghanaians are friendly and respond well to a smile. People are fairly relaxed, and will talk to anyone, regardless of whether they know a person or not. However, it takes a lot more time to establish a relationship; Ghanaians have to trust someone before they will really open up. People therefore spend a lot of time on small talk in an effort to get to know the other person, asking about schooling, hometown, and other personal questions. Once they get to know the other person, the business moves very quickly. In high contrast with our usual directness that the Dutch are famous for, taking our time to get to know people before diving into business is something we have to put some extra focus on.
