Wise, I note, to count information contained in it (11)
I believe the answer is:
intelligent
'wise' is the definition.
(thesaurus)
'i note to count information contained in it' is the wordplay.
I cannot really understand how this works, but
'i' is present in the answer.
'note' could be 'te' (musical note) and 'te' is present in the answer.
'information' could be 'gen' (gen can informally mean information) and 'gen' is found in the answer.
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for intelligent that I've seen before include "Capable of reason" , "Able to reason, bright" , "Knowledgeable" , "displaying brainpower" , "Perspicacious" .)
