Learn English Grammar: THE SUBJUNCTIVE – "I wish..."

Hi. Welcome again to engvid.com.
I'm Adam. Today we're going to look at something that I know students sometimes get
confused about. First of all, students ask me all the time,
'What is the subjunctive, the subjunctive voice in grammar?' First of all let me tell
you there are two different - or three even - different ways of looking at
the subjunctive. Usually people think, "The doctor recommended he go to hospital".
That is one example of the subjunctive.
What I want to look at today is the word "wish",
the verb "to wish", and how it is used,
because this is sometimes very confusing to students.
So, here I have a few examples of how to use the verb "wish".
"I wish I were rich." "He wishes he were taller." So,
the first thing you notice, I'm using "were",
not "was". Now, why? Because.
I'm sorry to say it like that,
but that's how it is.
Always use "were". Never use "was".
I, you, he, she, it, they,
we, "were", always. "I wish it would rain",
now here we're talking about an action verb,
"rain", like, "to come down", "rain",
so we use "would". "Bill Clinton wishes Hillary would be President".
Notice the capital P because President is a title here.
It's specific. So, this is called the subjunctive voice.
What we are talking about when we use the verb "wish" is a hypothetical.
What does hypothetical mean? Hypothetical means imaginary.
It's not real. So, anytime we use the verb "wish",
we're talking about something that isn't true and can't be true.
If it can be true, you'll probably use the word "hope",
but that's another story. So, how do we construct this? How do we set up
sentences? I'm going to write this down for you in a second and we'll look
at how to do this.
First, let's look at how we construct a sentence using "wish".
We begin with our subject, of course,
our verb "wish", and then we always have to remember to go one tense back.
What does that mean? If you have a present tense verb in the real situation,
when you talk about "wish", you talk about simple past.
If the real situation is simple past,
the "wish" would be past perfect,
