Doctor eats morel - it's somewhat rubbery (9)
I believe the answer is:
elastomer
'doctor eats morel it's somewhat rubbery' is the definition.
I can't tell whether this defines the answer.
'doctor eats morel it's somewhat' is the wordplay.
'doctor' indicates an anagram.
'it' becomes ''t' (abbreviation. e.g. in 'tis).
'somewhat' means to remove the last letter (some but not all of the word).
'eats'+'morel'+'t'='eatsmorelt'
'eatsmorelt' with its final letter removed is 'eatsmorel'.
'eatsmorel' with letters rearranged gives 'ELASTOMER'.
Can you help me to learn more?
(Other definitions for elastomer that I've seen before include "rubber-like substance" , "flexible material" , "Stretchy polymer such as rubber" , "Rubbery substance" .)
