Number of steps taken, trip (6)
I believe the answer is:
flight
This could be a double definition.
'number of steps' is the first definition.
'flight' can be an answer for 'steps' (I've seen this before). I'm unsure of the 'number of' bit.
'taken trip' is the second definition.
'flight' can be an answer for 'trip' (flight is a kind of trip). I am unsure of the 'taken' bit.
Can you help me to learn more?
(Other definitions for flight that I've seen before include "Exodus" , "The feathers on a dart or arrow" , "Movement through the air" , "Air transport - running away" , "Trip by air" .)
