Daughter in fog, the very centre (5)
I believe the answer is:
midst
'very centre' is the definition.
'midst' can be an answer for 'centre' (I've seen this before). I am unsure of the 'very' bit.
'daughter in fog' is the wordplay.
'daughter' becomes 'd' (genealogical abbreviation).
'in' is an insertion indicator.
'fog' becomes 'mist' (synonyms).
'd' put into 'mist' is 'MIDST'.
'the' is the link.
Can you help me to learn more?
(Other definitions for midst that I've seen before include "Thick (of things)" , "Where one is surrounded by other things" , "In the middle of (archaic or literary)" , "Blue dye; rainbow hue" , "Among, amid" .)
