Each editor admits silly blundering, being gullible (6,3)
I believe the answer is:
easily led
'gullible' is the definition.
Both the definition and answer are adjectives.
Maybe there's an association between them I don't understand?
'each editor admits silly blundering' is the wordplay.
'each' becomes 'ea' (abbreviation).
'editor' becomes 'ed' (abbreviation).
'admits' is an insertion indicator (to admit is to allow in).
'blundering' indicates an anagram (I've seen 'blunders' mean this).
'ea'+'ed'='eaed'
'silly' anagrammed gives 'silyl'.
'eaed' enclosing 'silyl' is 'EASILY LED'.
'being' acts as a link.
Can you help me to learn more?
(Another definition for easily led that I've seen is " Sequacious".)
