арча: pine tree
In the forests of Tajikistan pine trees, pistachio, walnut, almond trees and others grow.
Имсол дар майдони Дӯстии шаҳри Душанбе арчаи чароғон гузоштанд.
This year in the Friendship square of the city of Dushanbe they have put a lighted New Year’s tree (pine tree).
In Tajikistan people decorate trees for New Year’s in the same way people in some countries decorate trees for Christmas. So the word “арча” in that context is translated “New Year’s Tree” in the same way “Christmas tree” is used instead of “pine tree” when talking about it in the context of decorating it for Christmas.
