1. There are two main varieties of English spoken in Scotland: Scots and Standard Scottish English. Scots developed from Old English and is typically used by working classes, while SSE is used by educated middle classes. 2. Both varieties are distinct from other forms of English with their own pronunciations, grammatical structures, and lexicons. For example, Scottish English is usually rhotic and may use words like "out-with." 3. While Scots and SSE were once more distinct, the boundaries have blurred over time as many Scots speakers adopt elements of SSE. However, Scots remains influential in literature and some rural communities.
