Unmarried parent, experienced in a different way (9)
I believe the answer is:
otherwise
'a different way' is the definition.
(I've seen this before)
'unmarried parent experienced' is the wordplay.
'unmarried parent' becomes 'other' (I can't explain this - if you can you should believe this answer much more).
'experienced' becomes 'wise'.
'other'+'wise'='OTHERWISE'
'in' is the link.
Can you help me to learn more?
(Other definitions for otherwise that I've seen before include "White rose seen in a different way" , "White rose (anag.)" , "Apart from that" , "Alternatively" , "As an alternative - like white rose" .)
