- The phrase 'on spec' has no direct equivalent; it must be explained contextually.
Common Mistakes
- Using 'specs' (meaning glasses) interchangeably with 'spec' (specification). While 'specs' can be short for 'specifications', it's ambiguous.
- Treating it as an uncountable noun (e.g., 'We need more spec' is incorrect; use 'more detailed spec' or 'more specifications').
