Confused old boy destined to tour American college (10)
I believe the answer is:
obfuscated
'confused' is the definition.
Although both the answer and definition are past participle verbs, I can't understand how one could define the other.
'old boy destined to tour american college' is the wordplay.
'old boy' becomes 'OB' (abbreviation for a private school 'old boy').
'destined' becomes 'fated' (someone fated to do something is destined to it).
'to tour' indicates putting letters inside (to tour can mean to go around).
'american' becomes 'us' (abbreviation for United States).
'college' becomes 'c'.
'us'+'c'='usc'
'fated' going around 'usc' is 'fuscated'.
'ob'+'fuscated'='OBFUSCATED'
Can you help me to learn more?
(Another definition for obfuscated that I've seen is " Made unintelligible".)
