Locomotivity
I like this word. It has an interesting definition that our man Webster wrote in 1913. The definition remains the same in the 1928 dictionary and I don’t think the word appears in any current abridged dictionary.
Locomotivity
\Lo`co*mo*tiv”i*ty, n. [Cf. F. locomotivit[‘e].]
The power of changing place.
[1913 Webster]
