Town to which a man returns for half an hour (5)

'town to' is the definition.
I know nothing about this answer so I can't tell whether this works.

'a man returns for half an hour' is the wordplay.
'returns' shows that the letters should be reversed in order.
'for' is a charade indicator (letters next to each other).
'half' means to take half the letters.
'man' backwards is 'nam'.
'hour' halved is 'ur'.
'nam'+'ur'='NAMUR'

'which' acts as a link.

Can you help me to learn more?
