Bird's nest for example very high (4)

I believe the answer is:

soup

I'm a little stuck... Click here to teach me more about this clue!

'bird's nest for example' is the definition.
I can't judge whether this defines the answer.

'very high' is the wordplay.
'very' becomes 'so' (both can mean 'extremely').
'high' becomes 'up' (associated in meaning).
'so'+'up'='SOUP'

Can you help me to learn more?

(Other definitions for soup that I've seen before include "Mulligatawny or borscht?" , "Preliminary course" , "Bisque, for example" , "First course" , "Eskimo people" .)

I've seen this clue in The Sun.
