A Christmas tree is typically a pine or fir tree that has been cut down and brought into a home for the holiday season. It's a symbol of the season, and it's adorned with twinkling lights, colorful ornaments, and a shining star or angel at its top. The tree is decorated with the hopes and wishes of the family or individual who has chosen it, and it's a focal point of many holiday traditions, such as gift-giving and family gatherings.
