A ittle knowledge is a dangerous thing.

Another saying I like is:
The greater the island of knowledge, the longer is the shore of the unknown.

Or
The more you know, the more you are aware of what you don´t know.

These look at the opposite situation. People make bad choices because they think they know enough, but don´t (instead of asking for advice from someone with wider or more detailed knowledge). Etc.

Clients who look things up in the ´little red' dictionary and complain about a translation, because you have used a term that is only in the big technical dictionary, or only in some expert´s private glossary.
But at least they ask! The worst are those who just think you are wrong and alter the text!
There are plenty of examples.

Thank you for your suggestion and input. Very helpful. :-) I'll do that and see if I can narrow it down to one or two definitions at the most. Unfortunately, some folks here don't seem very interested in helping other than stating the obvious. Anyway, I'm leaving this discussion with the same level of insight I had when I first came in. Basically nill. :-) To be fair, yours was the most helpful comment I came across. Thanks again. :-)

"The phrase is self-explanatory. It doesn’t need elaboration."

Surely true. Can't argue with that.

Only one small bit missing:

"The phrase is self-explanatory if you already know what it means. It doesn’t need elaboration."

Same as with puzzles. Once you've solved a puzzle, the solution couldn't be more "obvious / self-evident / simple".

...that we have answered this. As Asker lives in the USA, I suggest that he has a live conversation with a native English speaker. We cannot do that through this forum.

I think these multiple definitions simply imply that the term has a very wide usage potential - i.e. can be used to describe a broad range of situations. I would browse online articles using the expression itself and tune into how the writer is using the phrase.
Personally I would say the phrase often carries a slight nuance of foreboding of some sort, or is used in such situations.

What I meant by "entirely different" is clearly the focus of each definition. Of course, they all coincide in that there's "little knowledge", but they each give a different explanation as to why little knowledge is dangerous. #1 says it's because people "make bad choices...", #2 says it's because you become "overconfident about [your] expertise...", #3 doesn't say why, and #4 says it's because " it gives you the illusion of knowledge when you, in fact, have only cursory knowledge of the subject". It sounds like I can take this expression to mean anything I want. lol. I could say, for example, that short answers don't boost my knowledge, hence they are dangerous because they might induce me to a mistranslation. :-) I cannot enter a zillion definitions for a single entry in the dictionary. I have to narrow them down to one or two at the most. Hopefully, I'll get some more elaborate answers here. :-)
