Chosen to succeed some of the lecturers (5)
I believe the answer is:
elect
'chosen' is the definition.
('elect' as an adjective can mean chosen)
'of the lecturers' is the wordplay.
'of' indicates the answer is hidden within the clue.
'ELECT' is hidden in the letters of 'the lecturers'.
'to succeed some' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for elect that I've seen before include "Vote into office" , "Bring to office" , "Choose for Parliament, say" , "Opt for; chosen" , "Select; chosen" .)
