A rather simple English sentence, with a couple of participles:



A man came walking down the street, whistling a happy tune.

Waku

Ko mite ta mwena laka me liki o ta polu, wilu a kia tami leyollu.
[ko mʲiːte ta mˠe̞ːna laːkɑ mʲeː liːkɨ oːta poːlu‿ɰᵊiːl aː kᵊiːa taːmʲi leːjolː]
There are no real participles in Waku; the verbs appear in their 'normal' form.

Here is a very preliminary translation for Nizhmel. I haven't done much work on participles and such, so this is basically something I made up on the spot. It's subject to change.

Nizhmel

Di kiu yisyen, kulnir shèmshal c’ayen t’alwo.
[tʲíː kʰʲýː ísʲen kʰú̞lnir ʂɛ`mʂal t͡ʂʼáːen tʼaloː]
"happy tune-whistling, man street-down walking came"

In Ngolu / Iliaqu, it's done with adverbial clauses introduced by lo. In these clauses, the subject can be present, but is generally omitted if it is identical with the subject in the main clause.

Meung would only have one participle here, though the method markers on verbs of motion are diachronically descended from participles:

Vrkhazhian doesn't have participles, so I use the present progressive verb stems.
I also made "whistle" an onomatopoeic verb f-r-f-r.

Yabushionese has neither participles nor a verb for "whistle", but I worked something out. To make it natural, I had to turn the whistling participle phrase into a relative clause, while the walking one is an adverbial phrase.

Yabushionese

The double adverbial ending appears when there is no further morpheme to be added to the verbal stem. In more formal language, the redundant one can be dropped.

Silvish has present participles, but it doesn't use them as often as English. For instance, "walking" gets translated as "con márce", literally "at a walk", and most speakers wouldn't even include that, unless it were needed for contrast.

Silvish:

N'um descendèi le czarréi (con márce), en sigglánt ne melodì urós.
[nõː dɛ.ɕãˈdaːɪ̯ lə tɕaˈreːɪ̯ (kə̃ ˈmɛɾ.tɕə) ə̃ sɪˈglã nə mɛlɔˈde ʊˈɾo]

A man came (walking) down the street, whistling a happy tune.

Your translation seems to be missing the "happy tune" part.

Picky, picky. Well, it just so happens "a happy tune" is implied as the object of all Silvish verbs unless explicitly stated otherwise. But to make you happy, I've added it to my translation.

[ahan tina kɛhɛrin ja visɔrin t͡ʃʉhʉn tiʉn]

I'm not sure whether to post here or not, because I don't have an actual translation at this point, but I do know how to do this:

came walking = walked + a prefix that has the meaning "come" when on a motion verb
whistling a happy tune = he whistled a happy tune + switch-reference so there's not really a "he"

In other words, no participles. There might not actually end up being any participles in the language either, it depends.

Hajás does this by distinguishing instrumental gerunds - that explain how an action was performed, such as "walking" in your sentence - and comitative gerunds - which barely tell us that something was ongoing at the same time as something else, such as "whistling". Of course these terms have nothing to do with cases, but they seemed the most suitable and easy to remember to me.
Anyway, the sentence would be:

Hajás
E sjend näzvelsel pëjnürj ej vímát, wolunug e qusjin lídamajnan.

Note that the translation of "came" is not accurate. I wouldn't normally use any other verb than "walk" here, but if I hadn't used "come" as well this post would have been useless.

Concerning the man at to walk him the man on the road: a tune of true jollity he whistled.

Not much in the way of participles in Mentolatian. The first one appears as the locative of a verbal noun, the second as a simple verb.

Arzuw is interesting in that it is one of those chain-derivation words you meet with rather frequently in the lanugage. O.Ment. *vezer (springtime) gives Mod.Ment. fezur; through its nom.pl. zrunnás we derive zrunan (to grow) and zeruwinno (growth, surging); through its pl. wrzinní we derive arzuts (joy) and its adjectival form arzuw. cuw (true, excellent) (< *ə1esu-) is a common adjectival intensifier.

Indonesian and German both seem to have a coocurence restriction on 'walk' and 'come', so I used 'came running'

This sounds really old-fasioned to me, though.
