laborate
To produce or develop (something).
archaic, intransitive, transitive
So astonishing do we know the effects of electricity to be, combined with the gases, that I rather incline to suppose these massive stones to be 'laborated,' as a chemist would say, in the vast regions of the air; not by the aid of bungling blacksmiths, Charlotte, but by the 'Great First Cause, least understood,' to whose goodness and wisdom we owe all our enjoyments, especially that surpassing happiness of being able to adore Him, and to admire His beautiful creation.
Where it comes from
Borrowed from Latin labōrātus, perfect passive participle of labōrō (“to labor, toil”), see -ate (verb-forming suffix).
