Family German chap leaves in error (7)
I believe the answer is:
clanger
'error' is the definition.
(I know that clanger is a type of bloomer)
'family german' is the wordplay.
'family' becomes 'clan' (I've seen this in another clue).
'german' becomes 'ger' (abbreviation).
'clan'+'ger'='CLANGER'
'chap leaves in' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for clanger that I've seen before include "error" , "Embarrassing blunder (with consequences that may reverberate)" , "Big mistake (when dropped)" , "Stupid mistake" , "Drop this to make a blunder" .)
