Left pair of Americans either side of IT chief (very attractive) (8)
I believe the answer is:
luscious
'very attractive' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for luscious that I've seen before include "Highly attractive, tasty" , "'Lush, delectable (8)'" , "Voluptuous" , "nicely rich" , "Richly sweet" .)
