What is the meaning of the English words
GROOMED SKI TRAIL?
A groomed ski trail is a path made by special equipment. The equipment cuts two parallel lines in the snow for the skis to follow.
If there is no groomed trail, you need to cut* your own trail in the fresh** snow – and that can be very hard work!
See BLOG 1 example: The skiing trails are groomed.
*to cut a trail means to make a new trail
**Fresh snow is new snow. This is also sometimes used to describe snow that has not been disturbed by walking, driving, skiing, etc.
