[lojban-beginners] Re: Conditionals--da'i etc.



Typo: the second one should be {.i da'i ganai broda gi brode}.

Off the top of my head I can think of basically 3 main conditional cases:
If p, which is definitely possible, then q
If p, which might happen, then q
If p, which is known to be false, then q

The case "if p, which is definitely true, then q" is also there but I can't see much reason to use that outside of very formal settings like mathematical proofs.

How do we express these, exactly? The way I understand {da'i} is that {.i ganai broda gi brode} is case 1 and {.i da'i ganai brode gi brode} is case 2. Do I understand these correctly? If so, how does case 3 (the contrary-to-fact case) work?

A related question that came to mind when I considered what {da'inai} means in the dictionary: does {nai nai} simply not do anything if attached to a UI? I ask because I see "supposing" as one thing, "in fact" as another, and "contrary to fact" as yet another. The latter two seem like they could potentially be opposites.
