Copy speech one's digested (4)
I believe the answer is:
echo
'copy' is the definition.
(I've seen this before)
'speech one's digested' is the wordplay.
'ECHO' is hidden in amongst the letters.
However, I'm uncertain how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for echo that I've seen before include "Noise heard again" , "Marked by heat" , "Imitate -- a nymph" , "'Greek nymph, she pined away until only her voice remained (4)'" , "In Roman mythology, the nymph who loved Narcissus" .)
