It's easy to be led astray about the unusual (6)
I believe the answer is:
doddle
'it's easy to' is the definition.
I can't tell whether this defines the answer.
'led astray about the unusual' is the wordplay.
'astray' indicates an anagram.
'about' is an insertion indicator.
'the unusual' becomes 'odd' (I've seen this before).
'led' anagrammed gives 'dle'.
'dle' placed around 'odd' is 'DODDLE'.
'be' is the link.
Can you help me to learn more?
(Other definitions for doddle that I've seen before include "Piece of cake" , "Something easily done" , "Snip" , "Easy crossword?" , "Easy task (informal)" .)
