Attendant checks returning dread in two ways (7)
I believe the answer is:
steward
'attendant' is the definition.
(steward is a kind of attendant)
'returning dread in two ways' is the wordplay.
'two ways' means two substitutions for 'way'.
'returning' says the letters should be written in reverse.
'dread' becomes 'awe' (I've seen this before).
'in' indicates putting letters inside.
'way' becomes 'st' (abbreviation for street).
'way' becomes 'rd' (short for road).
'awe' in reverse letter order is 'ewa'.
'st'+'rd'='strd'
'ewa' placed within 'strd' is 'STEWARD'.
'checks' acts as a link.
(Other definitions for steward that I've seen before include "Cabin attendant" , "Maritime waiter" , "Ship's waiter" , "Shipboard attendant" , "bailiff" .)
