Ready for marriage in white or in blue perhaps (6)
I believe the answer is:
nubile
'ready for marriage' is the definition.
(I've seen this in another clue)
'in blue perhaps' is the wordplay.
'perhaps' indicates an anagram.
'in'+'blue'='inblue'
'inblue' is an anagram of 'NUBILE'.
'in white or' acts as a 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 nubile that I've seen before include "Sexually attractive" , "Of marriageable age?" , "fit for match" , "Old enough for marriage" , "Old enough to marry" .)
