Here's a hypothetical situation in English:
-> Here you can see that if is followed by a verb in the Simple Past (won), while the second clause uses the Conditional Present (would buy).
Now look at the French:
-> Here you see that in French, si is followed by a verb in L'Imparfait (gagnait), while the second clause uses Le Conditionnel Présent (achèterait).
Here are more examples:
Si on gagnait au loto, on achèterait une maison.
If we won the lottery, we would buy a house.
Si tu venais avec moi, tu ne le regretterais pas.
If you came with me, you wouldn't regret it.
Je ne saurais pas quoi faire si j'étais toi.
I wouldn't know what to do if I were you.
Si j'étais riche, j'achèterais un appartement à Paris.
If I were rich, I would buy an appartment in Paris.
Note that to express hypotheses in French, you'll use L'Imparfait after si, and Le Conditionnel Présent in the second part of the sentence.
ATTENTION:
See other uses of L'Imparfait:
Expressing continuing action in L'Imparfait (imperfect tense)
Expressing habits or repeated actions in L'Imparfait (imperfect tense)

Hi Angela,
As this is a technical and not a language question can you re-post on the Help and support section where someone might be able to answer you?

There are three levels of "probability" with si-clauses:
If I run. -- Si je cours. (Possible)
If I ran. -- Si je courais. (Hypothetical)
If I had run. -- Si j'avais couru. (Impossible, it already happened.)
This is pretty much parallel what you would use in English.

So "if I could run" is a hypothetical case (#2). Therefore:
Si je pouvais courir.
The other two cases are:
Si je peux courir. -- If I can run
Si j'avais pu courir. -- If I could have run (If I had been able to run).

Hi Gregory,
The lesson is still under construction, so I will try and explain:
There are 3 types -
1. To express a likely situation using the present ------future/imperative
Si tu cours, tu auras ton train = If you run, you'll catch your train
Si tu peux, va chercher les enfants à l'école =If you can, go and fetch the children at school
2. To express an unlikely situation using the imperfect ------conditional present
Si tu lui parlais gentiment, il te répondrait = If you spoke nicely to him, he would answer you
Si tu travaillais à l'école, tu réussirais = I you worked at school, you'd succeed
3. To express an impossible situation (as in the past) using the PluPerfect -----Conditional past
Si tu lui avais répondu gentiment, il t'aurait répondu = If you had spoken to him nicely, he would have answered you
Si vous leur aviez donné de meilleures instructions ils ne se seraient pas perdus = If you'd given them better instructions, they wouldn't have got lost
Hope this helpsGregory

The Si-clause always uses the imperfect whereas the conditional is used only in the main clause. If you switch the order of clauses, naturally, the verb forms switch places too, so that the imperfect remakns with the Si-clause and the conditional with the main clause.

Hi David, I see what you mean. There is only one example which has the si-clause come second. Maybe a couple more examples and a sentence alerting the reader to this fact would help.

Hi Winfred,
here is the link to one of the conditional-lessons in the library. I think it serves as a good starting point to explore irregular verbs as well.
Greetings, -- Chris.
