[tlhIngan Hol] Klingon Word of the Day: lep

[Steven Boozer]

>> Klingon word: lep
>> Part of speech: noun
>> Definition: solid (state of matter)

I think the "state of matter" note was only to disambiguate which meaning Okrand is referring to.  Note BTW that we also have the quality {Sub} "be solid".

As we know, 

   In physics, a state of matter is one of the distinct forms in
   which matter can exist. Four states of matter are observable
   in everyday life: solid, liquid, gas, and plasma.
    < https://en.wikipedia.org/wiki/State_of_matter >

In addition to {SIp} "gas", we now have words for all four.

> Can I say {betgham 'oH bIQ'e'} or {lep 'oH nagh'e'} ?

I would think so.

> Or does "solid" and "liquid" mean something else? 
> How does {taS} "solution (liquid)" fit in here?

AFAIK our only example is from TalkNow!:  {DIr QanwI' taS} "suntan lotion".

> Would a plural form of those makes sens? {lepmey vIlegh}

Well, it would to a Changeling.  <g>
