Are There two levels of usage in English standard and substandard?
While there is a standard form of English that is widely accepted in formal writing and speech, there is not necessarily a definitive distinction between standard and substandard usage. Different varieties of English, dialects, and slang exist alongside the standard form, all of which have their own rules and conventions. It's important to remember that language is fluid and constantly evolving, with various styles and registers reflecting different contexts and communities.
