Potentially neat clue, it’ll be seen as characteristic of one liking mental activity? (12)
I believe the answer is:
intellectual
'seen as characteristic of one liking mental activity?' is the definition.
I can't tell whether this defines the answer.
'potentially neat clue it'll' is the wordplay.
'potentially' indicates an anagram (letters have the potential to spell a new word).
'neat'+'clue'+'itll'='neatclueitll'
'neatclueitll' is an anagram of 'INTELLECTUAL'.
'be' is the link.
Can you help me to learn more?
(Other definitions for intellectual that I've seen before include "Related to rational thought processes" , "Scholarly" , "Brainy person" , "Person with a highly-developed mind" , "Thinking type" .)
