Home is where the eggs are (4)
I believe the answer is:
nest
'home' is the definition.
(a bird's home)
'where the eggs are' is the wordplay.
I cannot really understand how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is present in the answer.
The remaining letters 'nes' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'is' is the link.
Can you help me to learn more?
(Other definitions for nest that I've seen before include "Bird's house" , "Ingredient of Chinese soup" , "Bird shelter" , "Structure to lay eggs" , "breeding-ground" .)
