Connection even clear in translation (9)
I believe the answer is:
relevance
'connection' is the definition.
(I know that relevance is a type of connection)
'even clear in translation' is the wordplay.
'in translation' is an anagram indicator (I've seen this in other clues).
'even'+'clear'='evenclear'
'evenclear' anagrammed gives 'RELEVANCE'.
(Other definitions for relevance that I've seen before include "Pertinence to the matter in hand" , "Point" , "Pertinent quality" , "Bearing" , "Suitability" .)
