Well.....
I think the discussion is going to get muddy very quickly because there is a plethora of gifts not limited to those listed in the texts cited and unless the discussion is selective and attending to one, two, or a small group of specific gifts then there will be dozens of conversations going that increasingly diverge from this opening post.
The being said, I'll offer an anecdotal account of what I believe to have been a word of knowledge gifted from God.
Many, many years ago I lived in and ran a group home for men with what we now call "developmental disabilities." Back then it was called "mental retardation." I lived with three men whose IQs were, respectively, 70, 55, and 45. The man with the 45 IQ rarely spoke. When he did speak in interpersonal exchange the only things he ever said were, "I hope," and "I don't know." I do not know whether anyone beside me had ever discovered "I hope," meant "yes," or some other affirmative response, and "I don't know" meant, "no," or some other negative response. I knew the man could speak because despite his low IQ he was a voracious reader and he often read out loud with impressive enunciation. One day a situation arose where a certain necessity for him to answer for himself and my getting frustrated with the staus quo intersected and I asked God to help me know what to say to effect an outcome (whatever that might be).
At this point let me digress because most of you know I'm a (recently retired) psychologist and as such I am well aware of how easy it is for a person to attribute their own thinking to God (and thereby justify no end of misguided belief and action). I get it. I'm a skeptic. A skeptic with faith

. What I'm currently posted could all be an imagination of my figment, but I firmly believe what ensued was from God.
I heard the voice, or had the thought (I'll let the reader decide), "Tell him it is okay to say, 'no,'" and that's what I did. "Fred, it's okay to say 'no.'" and Fred (not his real name) yelled, "NO!" Never in all my years before then nor afterwards did I ever hear Fred yell, much less yell as loud as he did that day. That one episode led to a huge change in Fred's life because after that Fred began to talk. First it was in clipped partial-sentences, then full sentences, then entire (but small) paragraphs, then conversation with others beside myself. I once had a discussion with the guy who had an IQ of 45 about the distinction between sacrifice and crucified and he followed the scriptures and the logic! I later learned that Fred had been "warehoused." His family, an otherwise loving, supported, and devoted family had set up a room on their home where Fred grew up with a television, comics, magazines, books, and a lounge chair so that when the family had to go out and couldn't/wouldn't take Fred with them, he could sit in comfort and occupy himself. He spent hours in a room with nothing more than a television for social stimulation every day of his youth. He was about 40 years old when I met him.
That one moment where he was given permission to disagree changed his life.
So don't any of you ever think I don't like disagreement.
Word.
