In two ways, wonder about attendant (7)
I believe the answer is:
steward
'attendant' is the definition.
(I know that steward is a type of attendant)
'in two ways wonder about' is the wordplay.
'two ways' can mean two replacements for 'way'.
'in' indicates putting letters inside.
'way' becomes 'st' (abbreviation for street).
'way' becomes 'rd' (short for road).
'wonder about' becomes 'ewa' (I can't explain this - if you can you should believe this answer much more).
'st'+'rd'='strd'
'strd' placed around 'ewa' is 'STEWARD'.
Can you help me to learn more?
(Other definitions for steward that I've seen before include "Airline cabin worker" , "Ship's waiter" , "Official at event" , "Shipboard attendant" , "Overseer" .)
