Pet turns over bone in food from Mexico (5)
I believe the answer is:
tacos
'food from mexico' is the definition.
'tacos' can be an answer for 'food' (I've seen this before). I'm not certain of the 'from mexico' bit.
'pet turns over bone' is the wordplay.
'pet' becomes 'cat' (cats are often kept as pets).
'turns over' says the letters should be written backwards.
'bone' becomes 'os' (synonyms).
'cat' back-to-front is 'tac'.
'tac'+'os'='TACOS'
'in' is the link.
Can you help me to learn more?
(Other definitions for tacos that I've seen before include "Foreign dish" , "Mexican food" , "Filled tortillas" , "Mexican dish" , "Mexican tortillas with various fillings" .)
