Has frightful anxieties and could be made sadder (6)
I believe the answer is:
dreads
'has frightful anxieties and could' is the definition.
I can't judge whether this definition defines the answer.
'made sadder' is the wordplay.
'made' is an anagram indicator.
'sadder' with letters rearranged gives 'DREADS'.
'be' acts as a link.
Can you help me to learn more?
(Other definitions for dreads that I've seen before include "Strongly fears" , "Looks ahead with apprehension" , "Sadder (anag)" , "Is in great fear of" , "Anticipates with horror" .)
