She gets playback from cassettes (5)
I believe the answer is:
tessa
'she' is the definition.
'playback from cassettes' is the wordplay.
'TESSA' is hidden backwards within the letters.
However, I am uncertain how the hidden word is indicated.
'gets' is the link.
Can you help me to learn more?
(Other definitions for tessa that I've seen before include "Girl's name; former savings account" , "Tax-exempt special savings account" , "Girl" , "Dahl or Jowell" , "Girl's name, forerunner of ISA" .)
