Expert writing Tips
Best practice
Use "could never" to express a strong sense of impossibility or inability, particularly when reflecting on past or hypothetical scenarios. For example, "I could never have imagined that I would live abroad."
Common error
Avoid using "could never" when "can never" is more appropriate. "Could never" implies a past or conditional inability, whereas "can never" expresses a present or future impossibility. For example, instead of saying "I could never understand quantum physics" (implying you tried and failed), say "I can never understand quantum physics" to express a general lack of ability.
