Stops and stands taking second short (9)
I believe the answer is:
restricts
'stops' is the definition.
The definition and answer can be both related to change as well as being verbs in their -s form.
Maybe there's a link between them I don't understand?
'stands taking second short' is the wordplay.
I cannot quite see how this works, but
'second' could be 're' (prefix meaning second in eg review, re-education) and 're' is located in the answer.
This explanation may well be incorrect...
'and' acts as a link.
Can you help me to learn more?
(Other definitions for restricts that I've seen before include "Places limits on" , "Puts a limit on" .)
