Stand and fall over a piece of wood (6)
I believe the answer is:
'stand' is the definition.
(I know that tripod is a type of tripod)
'fall over a piece of wood' is the wordplay.
'fall over' becomes 'trip' (I've seen this in another clue).
'a piece of wood' becomes 'od' (I am not sure about this - if you are sure you should believe this answer much more).
'and' is the link.
Can you help me to learn more?
(Other definitions for tripod that I've seen before include "oral test at school" , "support called for" , "Support needed" , "Stand for camera etc" , "Pay heed" .)
