There is going to be a match between ind vs aus.both sides are equally good.i cant say like india will win the game as both sides are equally good .what should I say?if india win the game I will give u 100 ruppees or if india won the game iwould give u 100 rp.i think first one should be the answer right as india winning the game is not an unlikely event as india also stands an equal chance of winning this game in speakers perspective.and al

I think I understand now.i have taken a lottery and is waiting for the results.my friend asked me what u will do if u win the lottery.now consider another example .I havent taken any lottery. So my friend asked if u won the lottery what would u do.
The difference bet the first and second sentence is that speaker thinks that it is a real possibility .he has taken a lottery so he might win the lottery.but in second sent ita just a hypo. Sent just like my father asking me If u become a prime minister what would u do .my father never expects me to be pm and all but just asking me what u would do in such imaginary situations.whereas in first sentence speaker thinks that although I have very less chance of winning the lootery I might w8n the lottery. But in 2nd sent he does not expect me to win any lottery cause I havent taken any lottery but is just asking for fun what u would do if u won the lottery.am i right?

Hello jino,

Yes, that's the idea – it sounds as if you understand it now. I just wanted to point out that you could still use the second conditional even when talking with someone who has a lottery ticket. Since, as Peter reminds us below, the odds of winning the lottery are very low (millions to one), one can certainly see winning as an unlikely event and use the second conditional to express that.

U didnt get my point. Thats not what I meant to say.my qn is that if the speaker thinks whatever he says is going to happen like he is 100 percent sure that it will happen then we will use first condirional. But if the speaker is not so sure like 50 50 chance then what we will use 1st conditional or 2nd one?

Hello jino,

I'm afraid you are confusing how the speaker sees an event with the real probability. Conditionals are about the speaker's perception, not the objective likelihood of something happening. Thus, I can say either of the following:

If I win the lottery, I'll buy a new house.

If I won the lottery, I'd buy a new house.

The only difference is my (the speaker's) perception of whether or not winning the lottery is plausible. In the first sentence I'm suggesting this is a real possibility in my life; in the second I'm suggesting that I know this is just a fantasy. But the objective probability has not changed (several million to one!).

Conditional forms require different possibilities, even if those possibilities are entirely fantastical. If a person is 100% sure that something will happen (i.e. is allowing for no other possibility) then they use a regular verb form without 'if', or use 'when' in place of 'if'.

Trying to base conditionals on real-world probability will not help you. Conditionals are about perception, not reality.

That is not what I meant to say.first conditionals is used for sure thingswhich will happen anyway.if it snows ,I wont go out. Snowing is a sure thing and it will happen right.but on ur conditional page it says that snowing might happen as an explanation.so first conditional can be used for things which is not 100 percent sure as well as for sure things.2 cond is used only for impossible things.so u should have given like snowing will happen as an explanation.why u given snowing might happen.or first conditionals can be used both for sure as well as for little sure like 50 percent ?this is what confussing me.u

Hello jino,

Using first versus second conditional has nothing to do with certainty or uncertainty – it has to do with possibility or likelihood, and always from the perspective of the speaker. One person might choose the second conditional whereas another might choose the first conditional – it depends on how they see the situation.

On ur conditional page in the example shown if it snows iwont go out.below that page it says that it might snow.will is used only for sure things right. But here it says it might.might means unsurality

Hello jino,

That's correct – 'might' can be used for possibilities, whereas 'will' can be used to express certainty.

We use would for impossible things or possible things?
