A hazard of learning? (8,5)
I believe the answer is:
educated guess
'learning?' is the definition.
Both the definition and answer are singular nouns.
Perhaps there's a link between them I don't understand?
'a hazard' is the wordplay.
I cannot really see how this works, but
'a' is found in the answer.
'hazard' could be 'guess' (synonyms) and 'guess' is present in the answer.
This explanation may well be incorrect...
'of' is the link.
Can you help me to learn more?
(Another definition for educated guess that I've seen is " good shot".)
