When I wrote the OP, I couldn’t actually remember which was correct. Part of the problem is that I grew up as a Mormon. Both the Book of Mormon and other Mormon scriptures were written in pseudo Jacobean English and don’t follow the correct rules.
I had googled it, and got hits for both phrases. Looking again, it seems that I was wrong. Oh well.
For the record, I’m a “he” and not a “she” and am a rather inexperienced ESL teacher.
Although I’m a native English speaker, having lived abroad for 25 years, mostly in Japan and mostly speaking Japanese during that time, my English can get really bad at times.
Lightening would be the process of making something lighter. “She just finished lightening her hair.”
Lightning is the stuff that comes out of the sky and scares the crap out of a room full of bored teenagers. “Thunderbolts and lightning, very, very frightening…”
Something like this coincidence happened to me once. I spoke to a woman at work whom I didn’t know well and called her by the wrong name. I wished the ground would open up.
Aren’t those moments great?
Something sort of similar happened for me. We were hosting one of our son’s strays, a guy who was supposed to be here just for a couple days. A couple weeks later, after he was using personal toiletries, not looking for a job or a more permanent place to stay, and was becoming almost demanding, we knew he had to go. I was elected to do the dirty deed. I took him out on the front porch to talk to him in private and as he realized I was throwing him out he became defensive and argumentative. Trying to retain control of the situation I told him I had already talked to the police (which I hadn’t)—and just then a cruiser came slowly down the street, something that rarely happens in this neighborhood. He went inside, got his stuff, and left. whew
Thing is, KJV or not, and given the lousy grammar sometimes displayed by ESL “native teachers” (who, as MrSquishy points out, are considered qualified by dint of having a passport from an English-speaking country), the joke works for those of us who have had to explain English grammar to the ESL teacher.
Because the subject of the sentence is “I”. The base sentence is “I have sopken”. “I has spoken” would be ungrammatical. “The Teacher” is simply a modifer of “I”, and does not impact the verb at all.
