Is "ultimated" a word? [closed]

Is "ultimated" a valid word?

For example:

Range requests were originally proposed by Ari Luotonen and John Franks, using an extension to the URL syntax instead of a separate header field. However, this approach proved less general than the approach ultimated used in HTTP/1.1, especially with respect to conditional requests. (source)

'Ultimated' is not a 'word' for two reasons

• it is not a common standard or an accepted variant to make a verb out of an adjective directly. It would be very colloquial (or even a sign of very gross invention) to do so. If it were done nowadays it would most likely mean 'to make ultimate'.

• in this context, a past participle is not expected but rather an adverb. This is probably a typo and what is most likely intended is 'ultimately'

...this approach proved less general than the approach ultimately used in HTTP__

I found ultimate listed as a verb in this online dictionary. Having found evidence that it is a legitimate (if not somewhat dated and out-of-vogue) verb, I checked the ultimate dictionary source, the OED.

The OED lists ultimate as a verb, meaning, "To carry to an end; to complete," with these three excerpts cited as example uses:

1849 E. H. Sears Regeneration (1859) iii. i. 131 Works are filled and vitalized by that angelic benevolence which is not complete until clothed and ultimated in action.
1866 B. R. Parkes Vignettes 399 My parents had seen my education ultimated in practical life.
1881 E. S. Holden Sir W. Herschel 53 His researches on the construction of the heavens would have been made; those were in his brain, and must have been ultimated.

By the way, just because it is a word doesn't negate what Mitch said above. As a matter of fact:

the approach ultimately used

does indeed appear more correct than

the approach ultimated used

so I agree that, in this case, it's probably an error in the text. Still, though, to ultimate the discussion, it's worth noting that ultimated can be used as a word.
