Guy, with hesitation, precedes one’s duennas (10)
I believe the answer is:
chaperones
'duennas' is the definition.
The answer and definition can be both people as well as being plural nouns.
Perhaps there's an association between them I don't understand?
'guy with hesitation precedes one's' is the wordplay.
'guy' becomes 'chap' (I've seen this in another clue).
'with' says to put letters next to each other.
'hesitation' becomes 'er' (sound used when hesitating).
'precedes' is a charade indicator (letters next to each other).
'chap'+'er'+'ones'='CHAPERONES'
Can you help me to learn more?
(Another definition for chaperones that I've seen is " our charges for trip are usually small".)
