**5.3 Factors determining language choice/use in multilingual situations**

Topic, role relation, and geography, according to Fishman [49], are elements that influence the concept of domain. In multilingual situations, he claims that topic can be a language regulator. When discussing specific topics, someone might, for example, adjust their language to that of the interlocutor. Role relation, according to Marjohan [67], is that the languages you use are decided by the interlocutors with whom you communicate. For instance, a father may converse with his mother, a child may converse with his mother, and a mother may converse with her child. He also says that locality influences the languages you use because of where the discussions take place. According to Marjohan and Tanner [67, 68], there are factors of choice to be setting in locale. The factors are content or topic, social distance and motivational factors. In social distance, there are two dimensions: vertical and horizontal dimensions. The vertical dimensions mean that the languages use are determined by the relative position of someone that is compared with others. Marjohan [67] States that you have to respect someone who is above you in terms of status, age or marital status. The horizontal dimensions refer to the relative closeness of someone with others. You tend to use a low code if you speak to someone who is close to you in terms of degree of friendship, sex, ethnic background, religious background or educational background. Someone has motivational factors when he or she is interested to speak with the interlocutors or interested about the topics even manipulative.
