Pass with badge sent over for huge cardinal (6)
I believe the answer is:
googol
'cardinal' is the definition.
(I know that googol is a type of cardinal)
'pass with badge sent over for huge' is the wordplay.
I cannot quite see how this works, but
'pass' could be 'go' (synonyms) and 'go' is found in the answer.
'over' could be 'o' (cricket abbreviation) and 'o' is located in the answer.
The remaining letters 'gol' 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 googol that I've seen before include "extraordinary figure" , "There's a huge amount!" , "Vast figure" , "Big number" , "Ten to the power of 100" .)
