Clinging type at the beach accommodation housing devil (6)
I believe the answer is:
limpet
'clinging type' is the definition.
I can't judge whether this defines the answer.
'the beach accommodation housing devil' is the wordplay.
'the beach accommodation' becomes 'let' (I can't justify this - if you can you should give a lot more credence to this answer).
'housing' means one lot of letters goes inside another.
'devil' becomes 'imp' (I've seen this before).
'let' enclosing 'imp' is 'LIMPET'.
'at' is the link.
Can you help me to learn more?
(Other definitions for limpet that I've seen before include "Mollusc adhering to rocks" , "Rock lover" , "Shellfish; type of mine" , "Clinging mollusc" , "Gastropod that sticks to rocks" .)
