Make sure you get the right dictionary

Is there a place in the world where so many languages can be spoken in a so limited area as it is the case here in French Guiana (and Suriname)?
The variety and number of languages will certainly strike the attention of anyone interested in languages.  This peculiar situation is likely the results or the combination of several elements:

• the survival of few original ethnic groups (e.g. Amerindians), despite the deforestation/urbanisation,
• the contribution or influence of the colonisation into the local languages (e.g. Creole),
• the various immigration flows (e.g. Chinese, Hmong communities),
• the vicinity with large linguistic groups (Portuguese and Spanish),

The map below provides a snapshot of this diversity:

Here below are tentatively  listed 19 living languages that are spoken in French Guiana:

• 5 European languages: French, Portugese, Dutch, Spanish, English
• 3 Asian languages: Hmong Njua, Hakka Chinese, Vietnamese
• 2 Creole languages: French Guiana Creole, Haitian Creole
• 6 Amerindian languages: Arawak, Palikúr, Kali'na, Wayana, Wayampi, Emerillon
• 3 Maroon dialects: Saramaccan, Aluku, Ndyuka

This list is certainly not exhaustive not taking into account dialects or languages imported by numerous immigrated people. For instance, the taki taki (known as sranan tongo = Suriname tongue) spoken by the Surinamese community of French Guiana (this language belongs to the creole group above) or even North levantine spoken by Arabic people originated from France...The permanent installation of Soyuz in CSG (ELS) will also bring more and more native Russians in French Guiana.
What makes also difficult to know exactly what we are talking about, is that a single language may show alternate names: For instance, Wayana language may be quoted as Ajana, Uaiana, Alucuyana, Guaque, Ojana, Orcocoyana, Pirixi, Urukuena, Waiano etc...
Even if some languages are spoken by a very limited number of persons (< 1000 for the Wayampi) and some other may even not be written, this diversity does reflect the culture of very ancient ethnic groups and the richness of the  local patrimony. For this reason, they need to be protected in order not to disappear due to the side effects of the globalisation.
Other information can be collected on the web page of the Ethnologue, languages of the world.
So, before packing your stuff to French Guiana don't mix up the dictionaries to bring with you :-)
