1. In what situations are the local and globalvarieties of spoken language used?2. What registers are appropriate to such situations?

Local and global varieties of spoken language are used in different situations. Local varieties, also known as dialects, are typically used in informal, everyday situations within a specific geographical area or among a particular social group. They reflect the culture and history of their speakers and can include unique vocabulary, grammar, and pronunciation.

Global varieties, on the other hand, are used in more formal, international contexts. They are often standardized and taught in schools, and are used in business, academia, media, and other domains where communication across different regions and cultures is necessary. English, for example, has a global variety known as Standard English that is used worldwide.

The register, or level of formality, used in a situation depends on the context, the relationship between the speakers, and the purpose of the communication. In informal, everyday situations, such as chatting with friends or family, a casual register is appropriate. This can include slang, colloquialisms, and non-standard grammar.

In formal situations, such as a business meeting, academic presentation, or news broadcast, a formal register is used. This includes standard grammar, formal vocabulary, and a more structured and coherent way of speaking. In these situations, using a local dialect may be seen as unprofessional or inappropriate, while using a global variety can facilitate clear and effective communication.
