Vehicles on the East End line (5)
I believe the answer is:
taxis
'vehicles' is the definition.
The answer and definition can be both man-made objects as well as being plural nouns.
Maybe there's an association between them I don't understand?
'on the east end line' is the wordplay.
'on' says to put letters next to each other.
'end' says to take the final letters.
'line' becomes 'axis' (axis is a kind of line).
The final letter of 'east' is 't'.
't' put next to 'axis' is 'TAXIS'.
Can you help me to learn more?
(Other definitions for taxis that I've seen before include "return to right place" , "Cabs" , "Cars with a driver for hire" .)
