What do you mean by, "liquid"? Do you mean it is all wet??
I was a weird phonetics term to me when I came across it in texts, but its history lies in the way Greeks described some of their sounds—interestingly from “ὑγρός” (moist) which would match up with your guess (“all wet”). In a nutshell, “liquids” are a class of sounds including English ⟨l⟩ and ⟨r⟩.
Also, what do you mean by, "nasal"? Do you blow it out your nose?
Oh yes. Nasal consonants feature airflow through the nose. Hence the name.
