Better to keep son wretched? (6)
I believe the answer is:
Here is my best explanation:
'wretched?' is the definition.
Both the definition and answer are adjectives. Maybe there's an association between them I don't understand?
'better to keep son' is the subsidiary indication.
'better' becomes 'cured' (after being sick**).
'to keep' means one lot of letters goes inside another.
'son' becomes 's'.
'cured' going around 's' is 'cursed'.
(Other definitions for cursed that I've seen before include "Swore", "Uttered imprecation, swore", "Blasphemed", "Damned", "Uttered profanities", "Anathematised", "Severely afflicted", "Detestable" and "Hateful".)
