Rigorous person in market securing point (8)
I believe the answer is:
martinet
'rigorous person' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'market securing point' is the wordplay.
'market' becomes 'mart' ('mart' can be a synonym of 'market').
'securing' indicates putting letters inside.
'point' becomes 'tine' (I've seen this in other clues).
'mart' going around 'tine' is 'MARTINET'.
'in' is the link.
Can you help me to learn more?
(Other definitions for martinet that I've seen before include "One demands exact conformity to rules" , "A strict disciplarian" , "Tyrant, one who demands strict obedience" , "Trite man becomes a tyrant" , "Strict disciplinarian - met train (anag)" .)
