Some free lectures for chosen people (5)
I believe the answer is:
elect
'chosen people' is the definition.
(thesaurus)
'some free lectures for' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'ELECT' is hidden within 'free lectures for'.
(Other definitions for elect that I've seen before include "Choose by voting" , "Preferred" , "Select; chosen" , "Appoint through ballot" , "Put in power by voting" .)
