Lady I take out? (5)
I believe the answer is:
lydia
'lady' is the definition.
(woman's name)
'i take out?' is the wordplay.
'take' becomes 'lyda' (I can't justify this - if you can you should believe this answer much more).
'out?' is an insertion indicator.
'i' put within 'lyda' is 'LYDIA'.
Can you help me to learn more?
(Other definitions for lydia that I've seen before include "Girl's name - ancient kingdom in Asia Minor" , "Old kingdom" , "'Love for --' (H.E. Bates)" , "lady" , "girl" .)
