Winnie the Pooh is our favorite ball of fluff that likes to eat honey in the Hundred-Acre Wood... but where does he get his name from? Specifically, where does "Pooh" come from?
I know that Winnie comes from a real bear that was the pet/mascot of a Canadian Army solider/battalion that was named after the city of Winnipeg. The bear eventually ended up in the London Zoo. A.A. Milne took his son Christopher Robin to the zoo where Christopher fell in love with Winnie and eventually named is own stuffed bear the same. That toy bear later became the inspiration for the Winnie the Pooh series.
However, this does not explain where "Pooh" comes from, especially since in-universe he is always called just "Pooh" or "Pooh Bear".
So where does the Pooh name come from?
Side bar (not part of the main question): Considering this was a children's series and "Pooh" is close to "poo" which is short for "poop" which is a euphemism for excrement, did "poo" mean the same thing back in 1926 as it does today? If it did, did A.A. Milne take this into consideration when naming his character?
