[Alessio]

I've always had some problems with this kind of sentence (past + would) in English, so I hope I got the meaning correctly: in the past, Mary said that the child would probably fall asleep soon, but "fall asleep" is in the past itself, i.e. the child has already fallen asleep or in any case is not expected to fall asleep now.

Italiano
Maria disse che il bambino si sarebbe probabilmente addormentato presto.

Maria disse che il bambin-o si sar-ebbe probabil-mente addorment-ato presto
Mary say.REMOTE_PAST that DEF.MS child-M REFL REFL-COND.3SG probable-ADV fall_asleep-PART.PAST soon
Mary said that the child would probably fall asleep soon.

È probabile che Maria abbia detto che il bambino si sarebbe addormentato presto.
/ε pro'babile ke ma'ria̯ 'abbja 'detto ke il bam'bino si sa'rεbbe addormen'tato 'prεsto/
è probabile che Maria abbia_detto che il bambin-o si sar-ebbe addorment-ato presto
be.3SG probable that Mary say.SUBJ.PAST.3SG that DEF.MS child-M REFL REFL-COND.3SG fall_asleep-PART.PAST soon
It is probable that Mary said that the child would fall asleep soon.

Notice that the second sentence uses the subjunctive (because we're not sure about Mary saying that), and both use the conditional in their second clause, much like in English.

I used sen doeto and l' e pprobablo ke ("doubtless" and "it's probable that", respectively) to translate "probably". There's also the adverb probablamen. I didn't use the adverb because I irrationally find it weird and cumbersome; don't know how native Silvophones feel about it

Ooh! Does liydevon trigger conditional mood?

Not specifically; liydevon is just "likely" or "propably", so it happens to coincide with conditional mood a lot. But the grammatical mood itself is actually triggered by the prefix di- here.

Well, I meant that liydevon's presence might cause the conditional to be used. The way I read your gloss, di- is (part of) the conditional mood, rather than a trigger for it.

Warning: my conlang is still work in progress and the lexicon might be changed in the future. Plus, due to my conlang's extremely bizarre grammar, glossing it is extremely difficult and inefficient. Several people in the conlang community have tried to gloss my conlang's sentences, but failed. I will try to find a compromise, anyway.

Anyway:

Mary said that the child would probably fall alseep soon

wmeriw leseyer tcot lefüci sese legi fözg

Well, I have not thought about that to be honest. In my corpus I could find some examples of liydevon (or its older synonym ter levon) with conditional mood and some without. I guess it depends on the situation.
