Device full of holes isn't rare, surprisingly (8)
I believe the answer is:
strainer
'device' is the definition.
(strainer is a kind of device)
'isn't rare surprisingly' is the wordplay.
'surprisingly' is an anagram indicator (a surprising ordering of the letters).
'isnt'+'rare'='isntrare'
'isntrare' anagrammed gives 'STRAINER'.
'full of holes' acts as a link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for strainer that I've seen before include "One gathers leaves" , "one full of holes" , "Tea leaf remover" , "Tea leaf catcher" , "Filter, sieve" .)
