English 'ketchup' came from Chinese, 'pyjamas' from Persian — languages constantly borrow from their neighbors. Language contact studies how tongues blend, trade words, and sometimes birth entirely new languages like creoles.
No language is an island
When speech communities meet, their languages influence one another. The mildest outcome is borrowing — words move between languages (English took 'ballet' from French). More intense contact can produce a pidgin: a simplified contact language with no native speakers, used for limited communication. When a pidgin becomes a community's first language, children elaborate it into a full creole.
The defining shift is nativization: a pidgin has no native speakers and a reduced grammar; a creole is acquired natively and develops the full expressive grammar of any first language.
Haitian Creole grew from French-lexicon contact in the colonial Caribbean and is now the native language of millions — a full language, not 'broken French'.
- A contact variety has no native speakers and a stripped-down grammar used only for trade.
- Later, a generation grows up speaking it as their first language.
- Name what each stage is called.
What you should see: The trade variety is a pidgin; once acquired natively and grammatically elaborated by children, it becomes a creole.
