Best practice
Use "could have seized" to express a missed opportunity or a potential action that was not taken in the past. It often implies a sense of regret or reflection on a different possible outcome.
Common error
Avoid using "could have seized" when you mean "could seize" or "could be seizing". The "could have + past participle" structure is specifically for hypothetical past events, not present or future possibilities. For example, avoid writing 'The enemy could have seized the city now' and consider alternatives like 'The enemy could seize the city now'.
