Yes, I think - here, they mark that those are separate words, and there is one in "ona" that separates syllables - if I got your meaning correctly?
on | i | o|na - right?
This may be a bit premature to ask this question, but does Polish have the same distinction in variety of ways to say "and" like Ukrainian does, where, although English only has one "and" there exist like an "and, BUT" variant as well as a simply "and additionally" version??? If I recall correctly it's not "ale" or "lecz" but I think possibly "a"??? Are "i" and "a" both "and" but with different contextual meanings???
Kobieta mówi i chłopiec słucha. Kobieta mówi, a chłopiec słucha. Both those sentences would be translated as having "and" in the middle to English.
"and additionally" - "oraz" (formal)
That's all I can think of right now. Polish wouldn't have Ukrainian "і" and "та" translated any differently, though - I think.
EDIT: "lecz" is a variant of "but." "i" and "a" mean the same, though in "i" the pressure is on the "togetherness" of both things that are happening; while in "a" it's more like "and, at the same time, there's a thing happening to somewhere/in someone else."
Do "і" and "та" have different contextual meanings?
EDIT2: Also, "a" is reserved for full sentences. When two people are together, "i" is what will be used between them ;).
"A" joins only simple sentences into bigger sentences but not words or objects. Though there is a second meaning where it means "and" like in "between ... and ... " like in "między niebem a ziemią" (between heaven and earth). Note that in this case you do not write the coma before "a" (in all other cases you do).
But normally "a" is a very neat word. It means "and" but it indicated that the sentences are somehow connected together logically or other way. "I" doesn't indicate any connection between the sentences joined.
The "comas between a" case is a bit more complicated and there are some additional situations when you definitely need or don't need the coma. But this can be a bit complicated right now :) Just note, that "między... a..." is not the only case.
Listening to the slow audio, it sounds more like "on w ona". Don't know if that even makes sense at all, but maybe it could get corrected? Or am I wrong on that?
Well, the slow "i" is a bit weird, but I definitely wouldn't call it "w".
The only thing we could change is disabling audio, but I don't think it's bad enough to disable it.
Polish ,,i" is like English ,,and". Other Polish word which also means ,,and" is ,,oraz", but ,,i" is more popular.
Shouldn't the stress (nearly) always fall on the penultimate syllable, that is, ona, and not ona?
From what I understand, many native speakers would say "Him and her" instead of "He and she", there's even a British sitcom named that way. And then other natives would tell them that it's wrong. Well, not my thing to decide, "Him and her" works here.
Unless you meant using such a phrase in a different manner than as a subject of a sentence.
