Tiny foolish person stopped short, a Dickensian (6,4)
I believe the answer is:
little nell
'person stopped short a dickensian' is the definition.
I know nothing about this answer so I cannot judge whether this works.
'tiny foolish' is the wordplay.
'tiny' becomes 'little' (similar in meaning).
'foolish' becomes 'nell' (I can't explain this - if you can you should give a lot more credence to this answer).
'little'+'nell'='LITTLE NELL'
Can you help me to learn more?
(Other definitions for little nell that I've seen before include "Miss Trent" , "Curiosity Shop girl (Dickens)" , "Dickens character" , "Dickens heroine (The Old Curiosity Shop)" , "orphan in work" .)
