Some Muscadet senator brought from the south, is put in a warm place (6)
I believe the answer is:
nested
'is put in a warm place' is the definition.
I can't judge whether this definition defines the answer.
'some muscadet senator brought from the south' is the wordplay.
'some' indicates the answer is hidden within the clue (some parts of the word are used).
'from the south' says the letters should be written backwards (in a down clue, letters go up).
'detsen' can be found hidden inside 'muscadet senator brought'.
'detsen' back-to-front is 'NESTED'.
Can you help me to learn more?
(Other definitions for nested that I've seen before include "intricate arrangement" , "Built a home" , "Settled in comfortably, snuggled up" , "Fitted inside one another, say set of tables" , "Settle in comfortably like a bird" .)
