A little Eskimo is to take part in winter sports (3)
I believe the answer is:
ski
'part in winter sports' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'a little eskimo is to' is the wordplay.
'a little' indicates a hidden word (a little bit of the clue).
'SKI' can be found hidden inside 'eskimo to'.
'take' acts as a 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" .)
