Really stunted rodents threw up sick worms (10)
I believe the answer is:
vermicelli
'really stunted rodents threw up sick worms' is the definition.
I can't judge whether this definition defines the answer.
'really stunted rodents threw up sick' is the wordplay.
'really' becomes 'very' (I've seen this in another clue).
'stunted' means to remove the last letter (the word is shorter than it usually is).
'rodents' becomes 'mice' (mouse is a kind of rodent).
'threw up' says the letters should be written in reverse (I've seen 'throwing up' mean this).
'sick' becomes 'ill' (similar in meaning).
'ill' back-to-front is 'lli'.
'very' with its final letter removed is 'ver'.
'ver'+'mice'+'lli'='VERMICELLI'
Can you help me to learn more?
(Other definitions for vermicelli that I've seen before include "Pasta in thin strands" , "Chocolate or pasta" , "Stringy pasta" , "Worm-like pasta" , "Very thin strings of pasta" .)
