One who danced well, with yen to travel (7)
I believe the answer is:
fonteyn
'one who danced' is the definition.
The definition suggests a singular noun which matches the answer.
'well with yen to travel' is the wordplay.
'well' becomes 'font' (I've seen this before).
'with' is a charade indicator (letters next to each other).
'to travel' indicates anagramming the letters (I've seen 'travelled' mean this).
'yen' anagrammed gives 'eyn'.
'font'+'eyn'='FONTEYN'
Can you help me to learn more?
(Other definitions for fonteyn that I've seen before include "Dame Margot --, ballet dancer" , "Margot ..., English prima ballerina" , "Margot ..., iconic English ballerina" , "'Margot ..., prima ballerina (7)'" , "Danseuse" .)
