Very, most of them.
Actually, now that you ask about it, I think -ve 'or' shouldn't count, as I think it's purely used to join nouns/verbs/adjectives within a sentence, in a way that's not at all necessarily in Wackernagel's position of course, like, say, senātus populusve.
Oh, that's the "que" that joins phrases within a sentence. I'm thinking of another -que here, the one that joins whole clauses. A rather famous example:=que, for instance, was inserted after the second conjuncted NP. (The famous example is of course Senatus Populus=que; 2P would be *Senatus=que Populus.)
1 Gallia est omnis divisa in partes tres, quarum unam incolunt Belgae, aliam Aquitani, tertiam qui ipsorum lingua Celtae, nostra Galli appellantur. 2 Hi omnes lingua, institutis, legibus inter se differunt. Gallos ab Aquitanis Garumna flumen, a Belgis Matrona et Sequana dividit. 3 Horum omnium fortissimi sunt Belgae, propterea quod
a cultu atque humanitate provinciae longissime absunt,
minimeque ad eos mercatores saepe commeant atque ea quae ad effeminandos animos pertinent important,
4 proximique sunt Germanis qui trans Rhenum incolunt, quibuscum continenter bellum gerunt.
1 Gallia is divided in three parts, one of which is inhabited by the Belgians, another of which by the Aquitani, and the third part by those who in their own language call themselves "Celts", or "Galli" in our language. 2 These peoples differ in language, institutions and laws. The Garonne river separates the Galli from the Aquitani, and the Marna and the Seine rivers separate them from the Belgians. 3 Amongst these, the Belgians are the strongest, because
they are furthest from civilization,
["and" because] merchants very rarely travel there for them to import the things that turn spirits effeminate,
4 ["and" because] they're closest to the Germans who live beyond the Rhine, who they're in constant war with. (Julius Caesar, On the Gallic War 1.1)
Here, proptereā quod 'because' takes three clauses (which I tried to creatively separate with line breaks and a little teal colour on the first two letters). The three subclauses are coordinated by two 2nd-position (Wackernagel-position) -que that attach to whatever the first stressed word is. First you see it with minimē 'very little' (part of the adverbial minimē saepe 'very rarely', literally "very-little often"), then with proximī 'closest' (proximī sunt Germānīs, close.SUPERL.NOM.PL be.3PL German.PL.DAT 'they're closest to [the] Germans [who...]').
Conversely, I'd say you shouldn't let yourself be misled by the orthography. Does what I said about them being able to interrupt even proper names not surprise you?As for the rest, though they’re certainly 2P, the orthography seems to indicate phonologically independent words rather than clitics. (The situation seems reminiscent of Tagalog, which also has 2P ‘clitics’ which are really separate words.)
Marcus Tullius Cicerō 'Mark Tully Chickpea'
Marcus enim Tullius Cicero vēnit. 'This is because M. Tullius Cicerō came by.'
They regularly break whatever phrase they can break if needed in order to be attached as enclitics:
Tribus igitur modis video esse a nostris de amicitia disputatum. (Cicero, On the Ends of Good and Evil 1.66)
'So I see that we have discussed friendship in three ways.'
Tribus modīs, three.PL.ABL way.PL.ABL, 'in three ways', is one noun phrase, but igitur needs to be attached at the end of the first stressed word (tribus 'three'), and so happily interrupts it. This is so pervasive with all the words I listed above (-ne, enim, autem, igitur...) I'd say it's evidence they're enclitics, even if written separately.
Also, for the most part, these pseudo-conjunctions/adverbs actually exclude each other. Basically you don't normally have two of them, like -que + enim, or enim + autem, or vērō + igitur. However, as an exception, -ne can indeed be combined with the others... You can have "Tribusne autem modīs [nōs...]" 'But is it that in three ways [we...]?'
In a nutshell, the same constructions you find in modern English.Interesting! So, if the clitics were abandoned, then what constructions arose to replace them?In Romance, every single one of them was abandoned. And mihi/tibi lost their ability to be in Wackernagel's position too.
