Answer 2

Explanation:

In linguistics, a compound is a lexeme (less precisely, a word or sign) that consists of more than one stem. Compounding, composition or nominal composition is the process of word formation that creates compound lexemes. That is, in familiar terms, compounding occurs when two or more words or signs are joined to make a longer word or sign, often however written in separate parts in English but not most other languages, e.g. press conference.
