Idiot's late checking French and German articles on hotel (10)
I believe the answer is:
dunderhead
'idiot's' is the definition.
(I've seen this before)
'late checking french and german articles on hotel' is the wordplay.
I cannot quite see how this works, but
'late' could be 'd' and 'd' is found in the answer.
'and' could be 'n' (common abbreviation for 'and') and 'n' is found in the answer.
'german' could be 'de' (language code) and 'de' is found in the answer.
'hotel' could be 'h' (phonetic alphabet: alpha, bravo, charlie etc.) and 'h' is found within the answer.
'on' could be 're' ('on' can be mean 'with reference to') and 're' is located in the leftover letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for dunderhead that I've seen before include "Dunce" , "dumbass?" , "fool" , "Stupid person" , "Ignoramus" .)
