Practices with transport (6)
I believe the answer is:
trains
This clue could be a double definition.
'practices' is the first definition.
The definition and answer can be both related to thinking as well as being verbs in their -s form.
Maybe they are linked in a way I don't understand?
'transport' is the second definition.
'with' is the link.
Can you help me to learn more?
(Other definitions for trains that I've seen before include "They're choo-choos to children" , "Locomotive-drawn rail cars" , "Exercises" , "Prepares by practice for performance" , "Aims; coaches" .)
