Burning and oddly cut as integrated circuit concludes (7)
I believe the answer is:
caustic
'burning' is the definition.
(thesaurus)
'oddly cut as integrated circuit concludes' is the wordplay.
'oddly' is an anagram indicator.
'integrated circuit' becomes 'ic' (abbreviation in electronics).
'concludes' says to put letters next to each other.
'cut'+'as'='cutas'
'cutas' anagrammed gives 'caust'.
'caust'+'ic'='CAUSTIC'
'and' is the link.
(Other definitions for caustic that I've seen before include "Biting (wit); burning" , "Scathing" , "Acrid" , "Chemically burning" , "Severe" .)
