School staff trained cats here (8)
I believe the answer is:
teachers
'school staff' is the definition.
Although both the answer and 'staff' are nouns, they are not in the same form of the noun.
'trained cats here' is the wordplay.
'trained' is an anagram indicator (train can mean to shape or manipulate).
'cats'+'here'='catshere'
'catshere' with letters rearranged gives 'TEACHERS'.
Can you help me to learn more?
(Other definitions for teachers that I've seen before include "beaks?" , "Instructors" , "Pedagogues" , "Coaches" , "Lecturers" .)
