• K, k  —  [PG]  The Letter “K” Is The Eleventh Letter Of The English Alphabet.  It Is Also The Eighth Consonant In The English Alphabet.

• Knowledge & Comprehension  —  [NG]  The Phrase “Knowledge & Comprehension” is not a Grammatical Term, and it is not even Grammatical Lingo.  However — you will see this Phrase (in various forms) — or you may see me use one of the Words of the Phrase:  “Knowledge” / (to) “Know” – Or – “Comprehension” / (to) “Comprehend” throughout this site, and all of GiveMeSomeEnglish!!!

But one thing you will very rarely see from me — is the use of the word “Understand”.  This is because it is a Metaphorical Word which not-only does NOT make ANY sense for how it is used.  But due to it’s ambiguity — the Word “Understand” can also be explained — with an equal amount of logic — to describe the complete opposite of what people THINK it means.
.

In-other-words — are you Metaphorically “Under” the thing which you Comprehend — as if you have a firm “Standing” and can now Metaphorically “Grasp” (another Metaphorical Synonym of “Comprehend”) that thing which you are firmly “Standing Under”;  And so that is why you have “Understanding”?
.

Or — is that thing “Under” YOU — and you have a firm “Standing” UPON that thing BECAUSE you Comprehend it?…  You tell me which one makes more sense.
.

Finally — because the Word is clearly a “Trap-Word” (a legal Term which is used because of it’s ambiguity to “trap” someone — due to the difference between it’s common mis-Comprehension & it’s TRUE Meaning & Usage)…  And because the Meaning of “Understand” (it’s TRUE Meaning) and it’s Usage are so different — I have almost completely eliminated it from my own personal Vocabulary — unless I am using it to speak about it’s TRUE Meaning.
.

And that TRUE meaning is:  To be “Under” the Authority (“Standing”) of another.

And the way that is is USED as a legal term is:  To cause someone to give away their own power & authority to another
.
.

Think about if you have ever seen an interaction between a person who is being arrested or questioned by a Police officer.  There will be MULTIPLE times during that interaction where-in the Police Officer will ask “Do You Understand?”
.

This is because — By Law — The Police Officer works FOR the citizen.  But when a citizen says, “Yes, I understand” — regardless of whether or not they actually Know & Comprehend what they are saying — they have just given their authority over to the Police Officer in that situation.  They have GIVEN the Police Officer the authority by officially stating:  “I Stand Under You”.
.

The same is true in any court case.  The judge has to ask, at many different points, if the defendant “Understands” what is happening.  If they say “No”, then the court can not proceed, because THEY do NOT have the authority.  It may be commonly thought that it is because the defendant must “comprehend” what is happening.  But the truth is the opposite.  If they Knew & Comprehended the Law — then they would never “Understand” anything — even if they did comprehend what was being said to them.  (Unless, of course if the person agreed with it.  Then they would “Understand” as an act of submission.)
.

Therefore — in it’s place — and In Every Situation where one would (mis-correctly) use the Term “Understand” — it can be replaced by the PROPER Words:  (to) “Know”, (to) “Comprehend”, or the combination of the two (to) “Know & Comprehend”.
