Dread about article that's light (7)
I believe the answer is:
feather
'light' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'dread about article' is the wordplay.
'dread' becomes 'fear' (synonyms).
'about' indicates putting letters inside.
'article' becomes 'the' (the definite article).
'fear' enclosing 'the' is 'FEATHER'.
'that's' is the link.
Can you help me to learn more?
(Other definitions for feather that I've seen before include "Part of a bird's plumage" , "One of a bird's waterproof covering" , "English plume (de ma tante?)" , "The fear (anag) - type of bed" , "manipulate oar" .)
