Conjunction of supine and PP with vera

[ftyers]

What is the least bad thing to do if we have "var" (vera) + Supine og PP? In principle for the var + Supine we want aux:pass(Supine, var) but for the PP we would want cop(PP, var).

# text = Men í 1986 var landið oyðilagt og á húsagangi.
# text[eng] = But in 1986 the country was ruined and bankrupt.
# labels = to_check ellipsis incomplete
"<Men>"
        "men" CC @cc #1->6
"<í>"
        "í" Pr @case #2->3
"<1986>"
        "1986" Num Dat @obl #3->6
"<var>"
        "vera" V Ind Prt Sg3 @aux:pass #4->6
"<landið>"
        "land" N Neu Sg Nom Def @nsubj #5->6
"<oyðilagt>"
        "oyðileggja" V Sup @root #6->0
"<og>"
        "og" CC @cc #7->9
"<á>"
        "á" Pr @case #8->9
"<húsagangi>"
        "húsagangur" N Msc Sg Dat Indef @conj #9->6
"<.>"
        "." CLB @punct #10->6

I have two ideas, maybe there are others:

1. Go with the "most complete structure before the conjunction", that would lead to aux:pass because it is the label that the Supine asks for.
2. Go with the globally most coherent "cop-Supn" is more coherent (in that Supn is like an adjective in some ways) than "aux:pass-PP".

Are you sure this is supine? Maybe I am biased by Swedish, but it seems to me that, regardless of whether it is used to adjectivally or passively, it is a past participle (with neuter agreement). The fact that it is coordinated with a PP would then disambiguate it to an adjectival use, and "cop" would be fine.

Good point, at least in Trond's analyser only the supine analysis is given.

But I see what you mean... the verb is type s20 which gives the perfect/past participle as oyðilagdur, which would be masculine, but it doesn't seem to have a neuter form for the past participle for this verb. In any case I'll check this and write again.
