Put back in its original condition by time in rose-red fluid (8)
I believe the answer is:
restored
'put back' is the definition.
(I've seen this before)
'time in rose-red fluid' is the wordplay.
'time' becomes 't'.
'in' indicates putting letters inside.
'fluid' indicates an anagram.
'rose'+'red'='rosered'
'rosered' with letters rearranged gives 'resored'.
't' put into 'resored' is 'RESTORED'.
'in its original condition by' is the link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for restored that I've seen before include "touched up?" , "Repaired a work to its original state" , "returned to its former condition?" , "Returned to former state" , "King Charles was" .)
