About my first wife starting geography in university (9)
I believe the answer is:
cambridge
'university' is the definition.
(Cambridge is an example)
'about my first wife starting geography in' is the wordplay.
'about' becomes 'ca' (abbreviation for 'circa').
'my first' becomes 'm' (gst letter of 'my').
'wife' becomes 'bride' (I have seen 'Wife of groom ' mean 'bride' so perhaps 'wife' could also mean 'bride').
'starting geography' becomes 'g' (I can't justify this - if you can you should give a lot more credence to this answer).
'in' is an insertion indicator.
'bride' enclosing 'g' is 'bridge'.
'ca'+'m'+'bridge'='CAMBRIDGE'
Can you help me to learn more?
(Other definitions for cambridge that I've seen before include "East Anglian city" , "Light blue university?" , "University city" , "English city" , "place of learning" .)
