Can you give me a short and clear definiton of metalingual, paradigm, phatic, and conative?

metalingual - changing between 2 specific languages that may only be : (->) arabic, from english, or the other way around. i know this as my mother is a linguist. it is only, however, w/ those 2 languages.

this was a correction donated on my behalf, tho u shud use the other answer also becoz we may both be right, just in different subject and profession and differing sciences.

i dont no any of the others tho, so lets go w/ the other persons stuff.

also, im 10, and have no idea wut im doing, so, again, ignore me.
