'one could go' is the definition.
I can't tell whether this definition defines the answer.

'father getting close to son' is the wordplay.
'father' becomes 'sire' (synonyms).
'getting' is a charade indicator (letters next to each other).
'close to' suggests the final letters (the 'close' to the word).
The final letter of 'son' is 'n'.
'sire'+'n'='SIREN'

'off' acts as a link.

Can you help me to learn more?
