Lover changes road with hesitation (6)
I believe the answer is:
adorer
'lover' is the definition.
(I know that adorer is a type of lover)
'changes road with hesitation' is the wordplay.
'changes' indicates an anagram.
'with' says to put letters next to each other.
'hesitation' becomes 'er' (sound made while hesitating - um, er).
'road' with letters rearranged gives 'ador'.
'ador'+'er'='ADORER'
(Other definitions for adorer that I've seen before include "One would love" , "someone in love" , "Lover; worshipper" , "One loves" , "Someone who loves greatly" .)
