Tasty school head gets paid off (5)
I believe the answer is:
sapid
'tasty' is the definition.
(I've seen this before)
'school head gets paid off' is the wordplay.
'head' indicates taking the first letters.
'gets' means one lot of letters go next to another.
'off' is an anagram indicator.
The initial letter of 'school' is 's'.
'paid' with letters rearranged gives 'apid'.
's'+'apid'='SAPID'
(Other definitions for sapid that I've seen before include "Tasty" , "Interesting" , "Pleasant tasting" , "Engaging" , "savoury'" .)
