A little Eskimo is to take part in winter sports (3)
I believe the answer is:
'part in winter sports' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'a little eskimo is to' is the wordplay.
'a little' says the answer is hidden in the clue (a little bit of the clue).
'SKI' is hidden within 'eskimo to'.
'take' is the link.
Can you help me to learn more?
(Other definitions for ski that I've seen before include "Glide ove snow" , "Walk on snow" , "Journey" , "Aid to movement on snow" , "runner in winter" .)
