In hotel I teach select group (5)
I believe the answer is:
elite
'select group' is the definition.
(I've seen this before)
'in hotel i teach' is the wordplay.
'in' indicates a hidden word.
'ELITE' can be found hidden inside 'hotel i teach'.
(Other definitions for elite that I've seen before include "Pick of the bunch" , "Selected as the best" , "Aristocratic" , "Cream, the pick" , "Type size; superior group" .)
