Able to shift the blame, perhaps, about Oscar and Victor (7)
I believe the answer is:
movable
'able to shift' is the definition.
I can't tell whether this defines the answer.
'blame perhaps about oscar and victor' is the wordplay.
'perhaps' indicates an anagram.
'about' indicates putting letters inside.
'oscar' becomes 'O' (phonetic alphabet: alpha, bravo, charlie etc.).
'and' says to put letters next to each other.
'victor' becomes 'V' (phonetic alphabet: alpha, bravo, charlie etc.).
'blame' is an anagram of 'mable'.
'o'+'v'='ov'
'mable' enclosing 'ov' is 'MOVABLE'.
'the' acts as a link.
Can you help me to learn more?
(Other definitions for movable that I've seen before include "Mobile" , "Not fixed" , "Able to be conveyed from one place to another" .)
