Gets wrong coach, taking Glen away (7)
I believe the answer is:
bungles
'gets wrong' is the definition.
I can't tell whether this definition defines the answer.
'coach taking glen away' is the wordplay.
'coach' becomes 'bus' (synonyms).
'taking' is an insertion indicator.
'away' is an anagram indicator (letters move away from their original places).
'glen' is an anagram of 'ngle'.
'bus' going around 'ngle' is 'BUNGLES'.
Can you help me to learn more?
(Another definition for bungles that I've seen is " messes up".)
