Lead out English chart-topper (5)
I believe the answer is:
adele
'chart-topper' is the definition.
I can't judge whether this defines the answer.
'lead out english' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'english' becomes 'e' (abbreviation).
'lead' anagrammed gives 'adel'.
'adel'+'e'='ADELE'
Can you help me to learn more?
(Other definitions for adele that I've seen before include "Female English singer-songwriter, b. 1988" , "girl" , "Female singer from London" , "Popular female singer" , "Woman" .)
