Cry in my cell, lacking covers (4)
I believe the answer is:
yell
'cry' is the definition.
(I know that cry can be written as yell)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for yell that I've seen before include "roar" , "Bawl, yowl" , "Loud sharp cry" , "Call out" , "Shetland isle" .)
