ETYMOLOGY
from Latin linguaci-, linguax (loquacious, talkative) (from lingua tongue + -ax [-acious]) + -ous
EXAMPLE
“…These and such like starting-holes and subtilties have made of Physick a Meander, a Wildernesse, and wild labirynth of incertainty and unstable formalities. We desire the linguacious Chymistry of these heads to tell us, how many bitter things there are in taste, which neverthelesse (according to the edict of that rule) are not hot at all? …”
