Some teachers get hurt (4)
I believe the answer is:
ache
'hurt' is the definition.
(synonyms)
'some teachers get' is the wordplay.
'some' indicates the answer is hidden within the clue (some parts of the word are used).
'ACHE' is hidden in the letters of 'teachers get'.
(Other definitions for ache that I've seen before include "Dull prolonged pain" , "Dull continuous pain" , "Similar" , "Throb - hurt" , "Shakespearean character" .)
