Greatly fear to peruse following final word (5)
I believe the answer is:
dread
'greatly fear' is the definition.
'dread' can be an answer for 'fear' (synonyms). I'm not certain of the 'greatly' bit.
'peruse following final word' is the wordplay.
'peruse' becomes 'read' (I've seen this in another clue).
'following' is a charade indicator (letters next to each other).
'final' says to take the final letters.
The final letter of 'word' is 'd'.
'read' after 'd' is 'DREAD'.
'to' is the link.
Can you help me to learn more?
(Other definitions for dread that I've seen before include "quail" , "fright" , "Disquiet" , "Frightful" , "Anticipate with fear" .)
