Some crossed Iran making return journeys (5)
I believe the answer is:
rides
'journeys' is the definition.
(I know this)
'some crossed iran making return' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'return' says the letters should be written in reverse.
'sedir' can be found hidden inside 'crossed iran making'.
'sedir' in reverse letter order is 'RIDES'.
(Other definitions for rides that I've seen before include "Comes through" , "Dries out for vehicle journeys" , "Journeys by horse or bicycle" , "Travels on something" , "Dries up and travels" .)
