Laid out Edward, having grown (7)
I believe the answer is:
dilated
'grown' is the definition.
Both the definition and answer are adjectives. Perhaps there's an association between them I don't understand?
'laid out edward' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'edward' becomes 'ted'.
'laid' anagrammed gives 'dila'.
'dila'+'ted'='DILATED'
'having' is the link.
Can you help me to learn more?
(Other definitions for dilated that I've seen before include "Made more open/wide" , "like pupils in the dark" , "Distended" , "Spoke at length" , "Enlarged" .)
