Why do you sometimes use an article before the noun when preceded by "Ez" and other times you don't? In a previous example, the articles were omitted and "meg" was used instead of "es", but the sentence had the exact same construction.
Would it still make sense if I used meg for and?
Yes, but then "és ez" changes to "ez meg". Watch the word order.
I can' t understand , when and how that word order with "pedig" "meg" "és" changes ... What's the difference ?
That's what I wrote, still says it's wrong.
Yes, it would.
I wrote "Ez a lámpa, ez meg a telefon" but I got it wrong.
"ez a lámpa ez pedig a telefon" is accepted.
Report it. It is a well worded answer.
