Almost over -- over from the word go (2,3)
I believe the answer is:
ab ovo
This might be a double definition.
'almost over' is the first definition.
The definition suggests a singular noun which matches the answer.
'from the word go' is the second definition.
(I've seen this before)
'over' is the link.
Can you help me to learn more?
(Other definitions for ab ovo that I've seen before include "From the very start" , "from the outset" , "from the word go" , "From the very beginning (Latin)" .)
