The word "Geschwindigkeit" is not the problem, but the naming 
conventions for variables.

The German language does not make the distinction between velocity and 
speed like in English, but uses the same word 'Geschwindigkeit' for both.

To distinguish scalars like speed from vectors like velocity, there is 
(and was since the 19th century) the practice to write little arrows 
above a variable, if a vector was meant.

But no such signs were used by Einstein.

Also missing were other signs or typographical hints, which would allow 
the reader to distinguish between values and functions, for instance.

The only used typographical distiction was the use of the text attribute 
'italic', which was occasionally used without any identifiable meaning.

He used Greek letters, too, but without a sufficiant reason.

His use of the Greek alphabet does not follow any obvious system.

E.g. he used Xsi, Eta and Zeta as name of the x, y and z-axis of the 
moving system, while the values along the Eta axis had the small greek 
eta as name.

But that same Eta axis was also called X later in the text.
