Mixed conditionals combine two different time frames in one conditional sentence.
Use past perfect in the if-clause and would + base verb for a present result of an unreal past condition.
Use past simple in the if-clause and would have + past participle for a past result of an unreal present situation.
| Use | Pattern | Example |
|---|---|---|
| Core form | If + past perfect, would + base verb | If I had saved more, I would be less worried now. |
| Variation | If + past simple, would have + past participle | If she were more organised, she would have met the deadline. |
| Advanced form | If + past perfect, might/could + base verb | If they had invested earlier, they might be leading the market now. |
Choose verb forms according to the time of the condition and the time of the result.
Use were for formal unreal conditions with I/he/she/it, especially in writing.
