Language change is variation over time in a language's phonetic, morphological,
semantic, syntactic and other features. Language changes over the years. This is at
vocabulary, pronunciation, dialect, accent, semantics and grammatical levels. One result of
ongoing changes is that a single language can develop into several languages. The early
stages of such development are apparent in differences among Australian, American,
Canadian, Indian and Irish English dialects, all of which have sprung from the English
spoken in Britain.
In order for different dialects to develop into separate languages, groups of speakers
must remain relatively isolated from one another, separated by physical barriers such as
mountain ranges and great bodies of water or by social and political barriers such as those
drawn along tribal, religious, ethnic, or national boundaries.
