One, say, often in local government starts to understand localism in end (7)
I believe the answer is:
regular
'one say often in local' is the definition.
I can't tell whether this definition defines the answer.
'government starts to understand localism in end' is the wordplay.
'government' becomes 'g' (abbreviation for government).
'starts to' indicates taking the first letters.
'in' is an insertion indicator.
'end' becomes 'rear' (I've seen this in another clue).
The first letters of 'understand localism' is 'ul'.
'g'+'ul'='gul'
'gul' going inside 'rear' is 'REGULAR'.
Can you help me to learn more?
(Other definitions for regular that I've seen before include "Happening frequently" , "Symmetrically arranged" , "He is a constant patron of 16 Down" , "Occurring at fixed intervals" , "At set intervals" .)
