After clearing out rubbish, order transport in regular form (7)
I believe the answer is:
rhombus
'form' is the definition.
(rhombus is a kind of form)
'after clearing out rubbish order transport in regular' is the wordplay.
I cannot quite understand how this works, but
'order' could be 'om' (Order of Merit) and 'om' is found within the answer.
'transport' could be 'bus' (bus is a kind of transport) and 'bus' is found within the answer.
The remaining letters 'rh' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for rhombus that I've seen before include "Equilateral parallelogram" , "Form of quadrilateral" , "Diamond-shaped figure" , "Lozenge shape" , "Type of quadrilateral" .)
