"Veep" actress Chlumsky (4)
I believe the answer is:
anna
'veep actress chlumsky' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for anna that I've seen before include "Girl's name (palindrome)" , "Dame -- Neagle" , "Girl - old Indian coin" , "Former one sixteenth of Rupee" , "Unit of length" .)
