I don’t worry about being in charge of elocution (7)
I believe the answer is:
diction
'elocution' is the definition.
(I've seen this before)
'i don't worry about being in charge' is the wordplay.
'worry' indicates anagramming the letters.
'about' indicates putting letters inside.
'being in charge' becomes 'ic'.
'i'+'dont'='idont'
'idont' with letters rearranged gives 'dtion'.
'dtion' enclosing 'ic' is 'DICTION'.
'of' is the link.
(Other definitions for diction that I've seen before include "Way of speaking or pronouncing" , "words for speech" , "One's manner of speaking or pronouncing words" , "Manner of enunciation" , "Elocution" .)
