American baseball legend forced into error of judgement (10)
I believe the answer is:
aberration
'error of judgement' is the definition.
'aberration' can be an answer for 'error' (thesaurus). I am not certain of the 'of judgement' bit.
'american baseball legend forced into' is the wordplay.
'american' becomes 'a' (common abbreviation - e.g. in organisation names).
'baseball legend' becomes 'berra' (I can't explain this - if you can you should believe this answer much more).
'forced' indicates an anagram.
'into' anagrammed gives 'tion'.
'a'+'berra'+'tion'='ABERRATION'
Can you help me to learn more?
(Other definitions for aberration that I've seen before include "irregularity" , "Unwelcome deviation from normal" , "moral lapse" , "mistake" , "Deviation from the accepted norm" .)
