"The musician waits inside, and the singer walks outside."
Translation:A zenész bent vár, az énekesnő meg kint sétál.
Or "on the other hand". This "meg" needs to be in the second position in its subclause. Being there, it is a synonym for "pedig".
The word "meg" cannot be anywhere else. If it were "pedig", we could move it to the first position, before "az énekesnő", but then it would mean something completely different, something like "despite that fact that".
So, be careful with the word order here.
Meg, similar to pedig, is there to emphasise a difference between the two terms, one inside, one outside. Like the English "however", or "whereas", but it can be well expressed with "and" in English as well.
Using és here would sound a bit weird, implying that musician and singer have a somewhat deeper connection.
I think that's my point. I understand the meaning in Magyar, but the English translation is weak and carries a different meaning by using "and" for everything. Then in many cases they want "meg" or "pedig" and consider it wrong if you use one or the other, when they don't indicate the underlying meaning accurately in English.
