So cold, queen's only dancing to preserve temperature (12)
I believe the answer is:
consequently
'so' is the definition.
(synonyms)
'cold queen's only dancing to preserve temperature' is the wordplay.
'cold' becomes 'c' (eg on taps).
'dancing' indicates anagramming the letters.
'to preserve' is an insertion indicator.
'temperature' becomes 't' (abbreviation).
'c'+'queens'+'only'='cqueensonly'
'cqueensonly' with letters rearranged gives 'consequenly'.
'consequenly' going around 't' is 'CONSEQUENTLY'.
(Other definitions for consequently that I've seen before include "As a result" , "thus?" .)
