Not able to eat frozen stuff can be observed (10)
I believe the answer is:
noticeable
'observed' is the definition.
Both the answer and definition are adjectives. Perhaps there's an association between them I don't understand?
'not able to eat frozen stuff' is the wordplay.
'to eat' indicates putting letters inside.
'frozen stuff' becomes 'ice' (ice is frozen water).
'not'+'able'='notable'
'notable' placed around 'ice' is 'NOTICEABLE'.
'can be' acts as a link.
Can you help me to learn more?
(Other definitions for noticeable that I've seen before include "Conspicuous" , "Prominent" , "Easily seen; clear" , "plain" , "impressive" .)
