Hello there..I think I have done the translation of that song earlier, so probably you refer to it
I will try to explain it to you. The word "Гора" means Forest- or Wood, whilst the word mountain refers more to the Macedonian word we use- "Планина"
So forest or wood it is the smaller one, while mountain it is more like the high mountains...That's why the used word "forest" it is more appropriate and exact translation of the word- "гора"
I hope I helped U..If you have any other questions U may ask me at any time..
Greetings from Macedonia, xxx
