Differentiate between language and dialectat least four points each

Here are four points differentiating between language and dialect:

1. Scope and System: A language is a comprehensive, independent system of communication with its own distinct grammar, vocabulary, and phonology. A dialect is a specific variety or sub-form of a language, sharing many core features with other dialects of the same language but having distinct regional or social variations.
2. Mutual Intelligibility: Speakers of different dialects of the same language can generally understand each other, although there might be some differences in pronunciation or vocabulary. Speakers of different languages, however, typically cannot understand each other without having learned the other language.
3. Standardization and Prestige: A language often has a standardized written form, established grammar rules, and is typically associated with national identity and institutional use (education, government). Dialects, especially non-standard ones, are primarily spoken, may lack a standardized written form, and can sometimes carry less social prestige.
4. Political and Social Factors: The distinction between a language and a dialect is not always purely linguistic; it can be heavily influenced by political, social, and cultural factors. Often, a "language" is a dialect with an army and a navy, meaning it has gained political recognition and status, while "dialects" are varieties that have not.
