Reminds one, in an alarming sort of way? (5,1,4)
I believe the answer is:
rings a bell
'reminds one' is the definition.
(I've seen this before)
'in an alarming sort of way?' is the wordplay.
I cannot really see how this works, but
'in' is found in the answer.
'an' could be 'a' and 'a' is found within the answer.
'way?' could be 's' (Compass direction - South) and 's' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for rings a bell that I've seen before include "Reminds one" , "What the town crier does" , "stirs up memories" .)
