I'm a little stuck... Click here to teach me more about this clue!

'brief accounts' is the definition.
The definition suggests a singular noun which matches the answer.

'a cadet gone off to get' is the wordplay.
'off' is an anagram indicator.
'to get' indicates putting letters inside.
'cadet'+'gone'='cadetgone'
'cadetgone' with letters rearranged gives 'anecdotge'.
'a' going inside 'anecdotge' is 'ANECDOTAGE'.

'some' acts as a link.
