One waking you in inept hotels in error? (11)
I believe the answer is:
telephonist
'one waking you' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'inept hotels in error?' is the wordplay.
'in error?' is an anagram indicator (I've seen 'in error' mean this).
'inept'+'hotels'='inepthotels'
'inepthotels' is an anagram of 'TELEPHONIST'.
'in' is the link.
Can you help me to learn more?
(Another definition for telephonist that I've seen is " Switchboard operator".)
