- Do not confuse with 'дубль-декер' (a non-standard calque); the established term is 'даблдекер' (for the bus).
Common Mistakes
- Using 'double-deck' as a verb (*'They double-decked the bus').
- Omitting the hyphen in the compound adjective ('double deck bus' is less standard).
- Using 'double-decker' to describe a single-level object with two of something (e.g., a twin-engine plane).
