Fear breaking card-reader (5)
I believe the answer is:
dread
'fear' is the definition.
(I know that dread is a type of fear)
'breaking card-reader' is the wordplay.
'DREAD' is hidden within the letters.
However, I am unsure how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for dread that I've seen before include "Anticipate with horror" , "Hairstyle" , "alarm" , "Disquiet" , "Dared to fear greatly" .)
