Sarcastic piece, no good, about India (6)
I believe the answer is:
biting
'sarcastic' is the definition.
(similar in meaning)
'piece no good about india' is the wordplay.
'piece' becomes 'bit' (synonyms).
'no good' becomes 'ng' (abbreviation).
'about' means one lot of letters go next to another.
'india' becomes 'i' (phonetic alphabet: alpha, bravo, charlie etc.).
'ng' after 'i' is 'ing'.
'bit'+'ing'='BITING'
(Other definitions for biting that I've seen before include "Cold - tart" , "Caustic or cutting - like teeth?" , "Sarcastic; very cold" , "Painful or stinging" , "Acerbic" .)
