Saddle and take horse round the German capital (5)
I believe the answer is:
ridge
'saddle' is the definition.
(I've seen this before)
'horse round the german capital' is the wordplay.
'horse' becomes 'ride' ().
'round' is an insertion indicator.
'capital' suggests taking the first letters.
The initial letter of 'german' is 'g'.
'ride' placed around 'g' is 'RIDGE'.
'and take' is the link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for ridge that I've seen before include "Backbone of a whale" , "Long narrow crest" , "A narrow raised strip in bridges" , "Bump between furrows" , "Narrow raised band on a surface" .)
