Slang

What does "sound" mean in British slang?

The structure is a simple adjective borrowed from its literal meaning of "healthy" or "solid," repurposed as general approval. It is used in British English, especially in London and surrounding areas, to mean good, acceptable, decent, reliable, or trustworthy, often describing a person or a situation. People typically say "He's a sound bloke" or "That's sound with me" or "Sound, I'll see you later." The term originated in 20th century British slang, possibly from the idea of "sound" as solid or unbreakable, and remains common across the UK in casual conversation.

Examples
That's a sound track you're playing.
