Cavendish is a proper noun most often used as a surname or place name, and is also associated with cultural items named after the Cavendish family. It denotes a specific, historically rooted identity rather than a common noun, typically pronounced with a two-syllable structure and stress on the first syllable in standard usage. The pronunciation cues emphasize a clear initial /ˈkæv/ followed by a softer /ən.dɪʃ/ or /-dɪʃ/ ending, depending on speaker and region.
