Take a look at the following linked PDF. I always point people to this when they have questions about ergativity. I've never seen a better breakdown of the different types of ergativity. It helps make it clear where languages like Basque that are morphologically ergative but syntactically accusative sit in the accusative <> ergative spectrum.

The man is happy.
Yep, this is OK.
Gaspard wrote:transitive verb:
(2) love[-3.SG] man-ERG mountain-ABS-PL
The man loves the mountains.
The language is VSO, and the second example shows that the transitive verb agrees with the ergative subject. Is it plausible to do this?
Yes, it's quite plausible, but making the verb agree with the ergative subject means that the language is morphologically ergative and syntactically accusative (as far as verb-noun agreement goes). AFAIK, more languages that have ergative features work like this than those that have syntactic ergativity (such as making the verb agree with the object).
Gaspard wrote:Would it be plausible to not mark subject and object at all on the verb? [I put it in brackets, since I don’t know yet if I want to mark the subject on the verb.]
I think so, yes. There are languages that don't mark person on the verb at all, and ergative languages are no different than accusative languages in terms of other features.
Gaspard wrote:(I’ve read somewhere that in ergative languages the verb tends to always agree with the absolutive part of the sentence. But I don’t see why in that case one doesn’t simply call the absolutive nominative, the ergative whatever, and the language a nom.-acc. language…)
If the language is purely ergative or close to it (it has morphological, syntactic, AND semantic ergativity, according to McGregor's terms), then yes, verbs would probably agree more with the absolutive. But again, most languages with ergative features tend to have a number of accusative features as well. It makes discussion of ergativity messy & confusing, & it's why McGregor's paper is so valuable. Rather than talking about languages being entirely ergative or accusative, it breaks down different areas of ergativity & accusativity so that we can look at it in a slightly more granular manner that is still organized well.
As to why it wouldn't simply be an accusative language at that point gets into the semantics of which argument is marked. I'm somewhat time-limited at the moment, but I can explain more later if needed.
Gaspard wrote:Now antipassive. As far as I understand it, the ergative subject of a transitive verb shifts to absolutive and the absolutive object shifts somewhere else (f. ex. oblique), like so:
(3) love-AP[-3.SG] man-ABS mountain-OBL-PL
The man loves the mountains.
I marked the antipassive on the verb, like a passive would be marked on the verb as well. The translation is the same, as English can’t simulate an antipassive construction.
This looks OK as well.
Gaspard wrote:What would you need the antipassive for? Well, for sentences like this:
(4) be.happy[-3.SG] man-ABS when see-AP-3.SG mountain-OBL-PL
The man is happy when he sees the mountains.
Since both subjects are the same they have to be in the same case (here absolutive), so the sentences can be connected. Otherwise the mountain would be happy…
Yep, I think ergative languages often require an antipassive in order to form relative clauses & such.
Also, the antipassive can have some subtle changes in meaning compared to a transitive construction, which can include definiteness or telicity. So your example above might mean "The man loves mountains" rather than "THE mountains". Exactly what the antipassive means or is used for varies from language to language, so if you are only using it for coordination, that's probably fine.
Gaspard wrote:Last thing: if you want to drop the ergative subject from a sentence like this:
(5) see-[3.SG] man-ERG mountain-ABS-PL
The man sees the mountains.
you just do so – there is no need for a passive voice. However I fear this doesn’t make too much sense if I mark the subject on the verb, since then I am not really dropping anything:
(6) see-[3.SG] mountain-ABS-PL
He sees the mountains. / The mountains are seen.
Yes, that's plausible as well. Again, ergative languages aren't any different from others, so some will allow arguments to be dropped, and others won't.
Also, you could still have a passive voice (if you want), but like the antipassive it might carry slight changes in meaning vs. your example #6.
Gaspard wrote:Is this the way an ergative language would work? Am I forgetting anything important?
It's the way SOME ergative languages work. Ergative languages are not all the same. They use ergativity in different ways, in different parts of the language. Take the time to really go through that PDF and understand it. It will really help you clarify why everything works the way it does, and then design your language to work how you want it to.
Start thinking about different types of verbs. The examples you used are emotions & perceptions, and often those work differently than other verbs in some languages. A couple good ones to think about:
The bread bakes.
The chef bakes.
The chef bakes the bread.
The hunter shot.
The bear was shot.
The hunter shot the bear.
In English, "bake" is an ergative verb, while "shoot" is accusative. So yeah, eventually you'll need to get into ergative, accusative, unergative, and unaccusative verbs. FUN!!!!! I would suggest to read the PDF, think about the above examples & other ones before you start reading too much about these types of verbs. You'll get yourself into a quagmire fast if you're not prepared for it.
Good luck, have fun, and feel free to ask more questions.
