I want to know the answer to the following question:
What is the meaning of the later-believed pre-Celtic Old European origin of London's name?
All the background I'm provided with is that "*(p)lowonida, meaning 'river too wide to ford', and suggested that this was a name given to the part of the River Thames which flows through London; from this, the settlement gained the Celtic form of its name,". Is that enough to answer the question?
Answer: yes
