The acquisition of interjections in early childhood

Interjections play an important role in communicative as well as non-communicative contexts, and their actual linguistic value and role were underestimated and misjudged for quite a long time:Interjections are among the most little studied of language phenomena; as one looks for references to them in the works of linguists, one is struck by the fact that they are very rarely mentioned, and where they are mentioned, it is usually only briefly and cursorily (James 1973: 1, The Syntax and Semantics of Some English Interjections). Only recently have linguists delved into the subject of interjection.
