Even providing transport (5)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
plane
This clue is a double definition.
'even' is the first definition.
('plane' can be similar in meaning to 'even')
'transport' is the second definition.
(plane is a kind of transport)
'providing' is the link.
(Other definitions for plane that I've seen before include "Aircraft - level surface - carpenter's tool" , "Smooth" , "Tree - figure - aircraft" , "barked?" , "Tool for smoothing wood" .)
