Speaks on her feet these days with politicians (2,4)
I believe the answer is:
ad libs
'speaks' is the definition.
Although both the answer and definition are verbs in their -s form, I can't see how they can define each other.
'her feet these days with politicians' is the wordplay.
I cannot quite see how this works, but
'her' could be 'lib' and 'lib' is present in the answer.
'days' could be 'd' (abbreviation for days) and 'd' is present in the answer.
The remaining letters 'as' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'on' acts as a link.
Can you help me to learn more?
(Other definitions for ad libs that I've seen before include "off-the-cuff remarks" , "speaks without forethought" .)
