ETYMOLOGY
from Latin motitat-, past participial stem of motitare (to move),
from motare (to set in motion, to keep moving) + -itare (-itate) + -ion
EXAMPLE
“… because muscles in this, scarce otherwise then in other functions, are strained; & therefore you rest a trembling Head upon a cush∣on, you shall soon stay the trembling, and free it from that motitation. And hence it is that we know this motion of the Head is voluntary …”
