Feel for (smirk) chicken chunks when talking (10)
I believe the answer is:
sympathise
'feel for' is the definition.
('feel for'->'sympathize' is in my internal thesaurus and 'ize'->'ise')
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for sympathise that I've seen before include "Express fellow feeling" , "commiserate" .)
