I've read that "would rather" has two different constructions; same subject and different subjects. Some of the examples have been listed below:
- I would rather they did something about it.
Question 1: Does it mean "I would prefer them to do something about it" at present moment or in the future?
- Rahul joined Engineering but he'd rather has joined medicine.
Question 2. Does it mean "He would have preferred to join medicine but he joined Engineering"
- I would rather you stayed at home tonight.
Question 3. Can't we just say "you would rather stayed at home tonight." Without changing the meaning of above sentence?
Note: I have read this question "I would rather did it myself" or "I would rather do it myself"? which is a bit similar to my question because both are about "would rather". But all the example sentences and questions that I have asked in my question are different.
