Fish to catch fresh eels? Not true (8)
I believe the answer is:
baseless
'fish to catch fresh eels? not true' is the definition.
I can't judge whether this defines the answer.
'fish to catch fresh eels?' is the wordplay.
'fish' becomes 'bass' (bass is a kind of fish).
'to catch' indicates putting letters inside.
'fresh' is an anagram indicator.
'eels' anagrammed gives 'eles'.
'bass' placed around 'eles' is 'BASELESS'.
Can you help me to learn more?
(Other definitions for baseless that I've seen before include "Without foundation, unsupported" , "Wrong, as a matter of fact" , "Without grounds" , "Without foundation, as rumours may be" , "Groundless, unfounded" .)
