Error to avoid around tame animal (7)
I believe the answer is:
misstep
'error' is the definition.
(misstep can mean an error or mistake)
'avoid around tame animal' is the wordplay.
'avoid' becomes 'miss' (miss can mean to avoid).
'around' shows that the letters should be reversed in order.
'tame animal' becomes 'pet' (pet is a kind of animal. I am not sure about the 'tame' bit.).
'pet' back-to-front is 'tep'.
'miss'+'tep'='MISSTEP'
'to' is the link.
Can you help me to learn more?
(Other definitions for misstep that I've seen before include "False move" , "bad move" , "Error" , "Badly judged move" , "Badly judged footing" .)
