Question about Alec confused Eric and Ernie? (6,3)
I believe the answer is:
double act
'eric and ernie?' is the definition.
I know nothing about this answer so I can't judge whether this works.
'question about alec confused' is the wordplay.
'question' becomes 'doubt' (synonyms).
'about' is an insertion indicator.
'confused' indicates an anagram.
'alec' anagrammed gives 'leac'.
'doubt' placed around 'leac' is 'DOUBLE ACT'.
Can you help me to learn more?
(Other definitions for double act that I've seen before include "Performance by a pair" , "Duo performance" , "What has four legs and makes us laugh" , "What was Hardy into" , "Partnership" .)
