Borne isn't the corresponding active voice of "to be born." It's a different verb altogether.

Born's archaic active form was "bear" or whatever Kantor said, but this is irrelevant in modern English.

"To be born" is active in English. A verb can only be passive if it has a related ablative of agent. "I am called by by father." "The ball was hit by the batter." I was born by my mother is grammatically incorrect. It is active in meaning as it is impossible for it to be passive.

That is exactly my point (that I admittedly discovered after consulting a dictionary).

You yourself asked what the active form of be born would be, but as it turns out be born is a separate verb, and as you already state in your last post, a verb in its active form. It doesn't have a passive form because it's not transitive.

I was borne by my mother would be the grammatically correct one though, bear is transitive. Putting aside the fact that it sounds awkward due to being so obvious and redundant. However maybe it wouldn't be in the case of Athens for example, who was borne by Zeus (then again since it was such a peculiar birth compared to the normal process, it does sound more normal to simply say born from his head or something along the lines).

We can just forget about bear, as that's archaic English.

Bear itself isn't archaic, but quite obviously the specific usage when the subject is the child, and the one giving birth is not mentioned, at some point became a new verb.

In any case this discussion should have answered your questions:

It is already active.

The verb would be bear here, hence borne. The child was borne by a surrogate mother isn't an archaic example.

Like I said, this is in British English. My dictionary lists born as a correct past participle of bear in US English.

This will never happen again, or I'll eat my hat!  I've seen this egregious error at so many other sites I just kind of assumed it was okay.  I apologize for failing all of you.  My new mission will be to regain your trust with the most badass grammar ever.

Thank you for finding all these so I don't have to cry into my lunch.

Grammar isn't exactly a strong point in this business, especially now that it's all much faster on the internet.  I've seen typos and grammatical gaffes at gamesindustry.biz, gamasutra, Fox News, MSNBC, and don't get me started on the other "games and gaming culture blogs" like Kotaku and Destructoid.  We've got dictionary.com, thesaurus.com, Google, and Wikipedia at our fingertips, and the whole world is forgetting how to write.  Sheesh.

The internet has made it worse indeed. I had to take an English language exam for studying Japanese, and one of the sections consisted of 20 sentences with four underlined components that were possibly wrong and a "correct" option, timed at 20 minutes. That was the section I feared the most because after years of progressively reading fewer books and spending more time on forums, chatting, blogs and the likes, I've gotten completely used to ignoring mistakes on all levels as long as it makes sense.

How about you don't tell me what to do? Why are you releasing all of this anger?

Yeah! The internet is like a publisher that prints anything, regardless of quality, and our brain is like a filter that eventually gets clogged by all the crap. Public formus are the worst offenders, of course. ;)
