Call second son Lambert to stir up faint memory (4,1,4)
I believe the answer is:
ring a bell
'stir up faint memory' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'call second son lambert' is the wordplay.
'call' becomes 'ring' (telephone call).
'second son' becomes 'Abel' (second son of Adam and Eve).
'lambert' becomes 'L' (synonyms).
'ring'+'abel'+'l'='RING A BELL'
'to' is the link.
Can you help me to learn more?
(Other definitions for ring a bell that I've seen before include "Formally declare (appointment)" , "Town crier may" , "What door-to-door salesman's wont to do" , "Beginning to arouse a memory" , "sound vaguely familiar" .)
