Neighbor of Lucy and Ricky (5)
I believe the answer is:
ethel
'neighbor of lucy and ricky' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ethel that I've seen before include "- Barrymore, actress" , "girl" , "Lethe (anag) -- Barrymore or Merman" , "Dame - Smyth, Eng. composer, suffragette" , "chapel" .)
