Unique among the globe’s continents, Antarctica lacks an indigenous human population. The White Continent proper wasn’t even definitively visited by people until the 19th century. It goes without saying, then, that there’s no native tongue here, and no official Antarctica language.

But between the  South American ports and sub-Antarctic ports of call, to the conversations of your fellow cruise passengers, and the greetings you might receive when visiting a research base, a trip to Antarctica will likely expose you to some delightful lingual diversity.

Before you step aboard, you’ll find that Spanish is the dominant language in the two most significant South American launchpads for Antarctic voyages: Ushuaia, Argentina and Punta Arenas, Chile. That said, English is extensively taught in both Argentina and Chile and therefore quite widely spoken if your Spanish is a little rusty (or non-existent!). If you’re thinking of traveling more widely in South America pre or post-Antarctica though, a good English-Spanish dictionary will serve you well and knowing a few basic Spanish phrases will be appreciated.

Unsurprisingly, given it’s the most commonly spoken language in the world and the most prominent in international affairs, English predominates on Antarctic cruises and tours, but multilingual services are often readily available, with some operators offering lectures and excursions in French, German, Japanese and Spanish, amongst others.

For those cruise-goers undertaking longer expedition cruises that include visits to the various sub-Antarctic islands, you’ll find that English is the official language of the Falklands, having been settled by the French and British in the late 18th century, as well as in South Georgia and the South Sandwich Islands, which, like Antarctica, never supported a native human population. Spanish remains a significant minority language in the Falkland Islands as well.

From Pakistan to Bulgaria, from South Africa to Japan, better than 40 countries maintain close to 70 research bases in the Antarctic, anchoring a seasonal, science-oriented population that ranges from about 4,000 to 5,000 in summer to a thousand or so in winter. Examples of these research stations include McMurdo (the largest) and the Amundsen-Scott South Pole Station (both U.S.), Vostok Station (Russia), Esperanza Base (Argentina), and Davis Station (Australia).

The multinational character of Antarctica’s scientific operations shakes out to a wonderful plethora of languages spoken on the White Continent, from the bases themselves to the temporary field camps.

What is the most spoken language in Antarctica? English is the most widely used, partly because it’s the default lingua franca of the scientific world and partly because researchers from English-speaking countries—namely Australia, New Zealand, the U.S., and the U.K.—outnumber all others on the White Continent.

But the diversity of nations maintaining research bases—and the diversity of international researchers represented at individual stations—ensure that many other lingoes are prominent on the White Continent, and that there’s no main language in Antarctica. Hundreds of scientists here hail from Spanish-speaking countries, particularly Argentina but also Chile, Peru, Ecuador, Spain, and others. Other languages spoken in Antarctica include Russian, French, Chinese, Italian, Norwegian, Japanese, Dutch, and Czech—just to name a few.

How many languages are spoken in Antarctica? It’s impossible to say, but many dozens, surely—not counting the myriad tongues represented by the thousands of tourists who visit the bottom of the world each year.

While there may be no official language in Antarctica, amazingly a study published in the Journal of the Acoustical Society of America has suggested there to be an Antarctica accent evolving, albeit in its embryonic stages. The Antarctica accent has longer vowel sounds, and also involves a physical change too, with participants pronouncing the “ou” sound from the front of their mouths rather than the back of their throats.

Study author and Professor of Phonetics and Speech Processing at the Ludwig-Maximilians University of Munich, Jonathan Harrington, said: “The Antarctic accent is not really perceptible as such – it would take much longer for it to become so – but it is acoustically measurable.”

Tourists shouldn’t worry about developing the accent however, as so far it has only been detected in staff spending a considerable amount of time in the region, the study having involved recording the voices every six weeks of a small number of individuals from England, the US, Germany, and Iceland participating in the British Antarctic Survey (BAS) who were overwintering on the continent.

No single authority oversees geographic place names (aka toponyms) in Antarctica, which encompasses a variety of languages reflecting the rich international legacy of early Antarctic exploration and exploitation as well as today’s vibrant scientific activities. There’s the East Antarctica volcano Gaussberg (German), for example; the coastal point of Pourquoi Pas (French); and Spillway Icefall (U.S.).

An aboriginal word from about the opposite side of the world shows up prolifically in Antarctica: nunatak, taken from the Inuit language, which refers to a mountain peak projecting above surrounding ice and therefore finds plenty of currency on the ice-smothered White Continent—at the Neptune Nunataks, Krasnaya Nunatak, and Catenary Nunatak, plus many, many others.

The many different languages spoken at Antarctic research stations, not to mention sightseeing cruise ships, serve as a stirring reflection of the White Continent’s unique nonpolitical status, the spirit of international cooperation and scientific inquiry that led to the adoption of the Antarctic Treaty, and the preciousness of this polar wilderness to all of humanity.
