E Elgar right to go back - score definitely subpar (5)
I believe the answer is:
eagle
'score definitely subpar' is the definition.
I can't tell whether this defines the answer.
'e elgar right to go back' is the wordplay.
'right' becomes 'r' (abbreviation).
'to go' indicates named letters should be taken away.
'back' is a reversal indicator.
'elgar' with 'r' taken away is 'elga'.
'elga' in reverse letter order is 'agle'.
'e'+'agle'='EAGLE'
Can you help me to learn more?
(Other definitions for eagle that I've seen before include "Raptor" , "good score" , "experts are putting more than albatross?" , "Hook-billed bird of prey -- old US $10 coin" , "Flyer" .)
