It's clear that it would be inadvisable to refuse Dana recklessly (7)
I believe the answer is:
visible
'it's clear that it' is the definition.
'visible' can be an answer for 'it's clear' (thesaurus). I am not certain of the rest of the definition.
'inadvisable to refuse dana recklessly' is the wordplay.
'to refuse' indicates named letters should be taken away.
'recklessly' indicates anagramming the letters.
'inadvisable' with 'dana' taken away is 'ivisble'.
'ivisble' anagrammed gives 'VISIBLE'.
'would be' acts as a link.
Can you help me to learn more?
(Other definitions for visible that I've seen before include "In view" , "Showing up" , "Capable of being seen" , "Perceptible by the eye" , "Able to be seen" .)
