Nominal composition
Nominal composition is the process of putting two or more words together to form another word, although the new word does not necessarily have the same meaning. The new word is a compound word.
The process occurs readily in North Germanic languages for different reasons. Words can be concatenated both to mean the same as the sum of two words (such as Pressekonferenz - German for press conference) or where an adjective and noun are compounded (e.g. hvidvinglas - Danish for white wine glass).
