Moves like grounded airmen? (5)
I believe the answer is:
taxis
'moves' is the definition.
The answer and definition can be both to do with motion as well as being verbs in their -s form.
Perhaps you can see an association between them that I don't see?
I don't understand the remainder of the clue.
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" .)
