Question

Define meta language?
Define Vocatives.
In terms of linguistics

Answer 1

define meta language
Broadly, any metalanguage is language or symbols used when language itself is being discussed or examined.[1] In logic and linguistics, a metalanguage is a language used to make statements about statements in another language (the object language). Expressions in a metalanguage are often distinguished from those in an object language by the use of italics, quotation marks, or writing on a separate line.[citation needed] The structure of sentences and phrases in a metalanguage can be described by a metasyntax.[2]

define vocative

The vocative case (abbreviated voc) is the case used for a noun that identifies a person (animal, object etc.) being addressed or occasionally the determiners of that noun. A vocative expression is an expression of direct address by which the identity of the party spoken to is set forth expressly within a sentence. For example, in the sentence "I don't know, John," John is a vocative expression that indicates the party being addressed, as opposed to the sentence "I don't know John" in which "John" is the direct object of the verb "know."
