Reminiscences? No way seaweed will grip one (9)
I believe the answer is:
nostalgia
'reminiscences? no' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'way seaweed will grip one' is the wordplay.
I cannot really understand how this works, but
'way' could be 'st' (short for street) and 'st' is located in the answer.
'one' could be 'i' (Roman numeral) and 'i' is found within the answer.
'seaweed' could be 'alga' (singular form of 'algae') and 'alga' is found within the remaining letters.
The remaining letters 'no' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for nostalgia that I've seen before include "longing for home and family" , "Sentimental feeling of analogist" , "severe homesickness" , "Wistful remembrance of analogist" , "Fond memories" .)
