Motorcyclist, British one, meeting king with hesitation (5)
I believe the answer is:
biker
'motorcyclist' is the definition.
(I've seen this before)
'british one meeting king with hesitation' is the wordplay.
'british one meeting king' becomes 'bik' (I can't justify this - if you can you should believe this answer much more).
'with' says to put letters next to each other.
'hesitation' becomes 'er' (sound made while hesitating - um, er).
'bik'+'er'='BIKER'
Can you help me to learn more?
(Other definitions for biker that I've seen before include "Rider" , "Hell's Angel?" , "Motorcycist" , "Motorcyclist" .)
