Found in bank, lecturer's joint (5)
I believe the answer is:
ankle
'joint' is the definition.
(joint of the body)
'found in bank lecturer's' is the wordplay.
'found in' says the answer is hidden in the clue.
'ANKLE' is hidden within 'bank lecturers'.
(Other definitions for ankle that I've seen before include "Major foot joint" , "Bone over foot" , "Joint between foot and leg" , "Major joint in lower limb" , "Narrow part of leg" .)
