Once more my father went outside in great fear (5)
I believe the answer is:
dread
'great fear' is the definition.
(I've seen this before)
'once more my father went outside' is the wordplay.
I cannot really see how this works, but
'once more' could be 're' (prefix in words like 're-emerge' or 're-enter') and 're' is found in the answer.
'father' could be 'da' (da can mean dad) and 'da' is found in the remaining letters.
A single letter 'd' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
'in' is the link.
Can you help me to learn more?
(Other definitions for dread that I've seen before include "alarm" , "Terror" , "Hairstyle" , "Terrible fear" , "Be very averse to" .)
