Master Latin -- it enables general education initially (5)
I believe the answer is:
liege
'master' is the definition.
(thesaurus)
'latin it enables general education initially' is the wordplay.
'latin' becomes 'l'.
'initially' indicates taking the first letters.
The first letters of 'it enables general education' is 'iege'.
'l'+'iege'='LIEGE'
(Other definitions for liege that I've seen before include "Old sovereign" , "Feudal (lord); vassal" , "Bound to render feudal service" , "Belgian city or ancient lord" , "Belgian city or feudal superior" .)
