When it comes to the correct spelling of the metallic element with the atomic number 13, there seems to be a perennial debate – should it be spelled as “aluminum” or “aluminium”? I often encounter this question from my students, particularly those aiming to excel in the International English Language Testing System (IELTS) exam. The answer to this seemingly trivial question is both fascinating and enlightening, as it not only delves into linguistic preferences but also historical and cultural factors.
First and foremost, it is crucial to understand that both spellings are, indeed, correct. The discrepancy arises due to the differences between American and British English. In the United States, the preferred spelling is “aluminum,” while in the United Kingdom and other English-speaking countries, including Australia, Canada, and New Zealand, the term “aluminium” is typically used. This variation stems from the efforts of influential 19th-century chemists who discovered and named the element.
In 1807, English chemist Humphry Davy coined the term “alumium” for the metal, using “ium” as a suffix, which was common for metallic elements at the time. However, in 1812, Davy revised the spelling to “aluminum” to adhere to the “ium” suffixes of other elements such as calcium, strontium, and barium. This original American spelling caught on and was widely accepted in the United States.
Meanwhile, in 1825, Danish chemist Hans Christian Ørsted proposed the alternative spelling “aluminium” to maintain consistency with other elements ending in “ium” and to align with the patterns of Latin-based language morphology. This proposal gained traction among chemists and became the favored spelling in the United Kingdom and throughout the British Empire.
To illustrate this linguistic divergence, let us consider a few examples. In American English, one might say, “I need to replace the aluminum siding on my house,” while in British English, the preference would be, “I need to replace the aluminium cladding on my house.” Similarly, an American might discuss the properties of aluminum foil, while a Briton would refer to the qualities of aluminium foil.
While these spelling variations may seem trivial, they have real-world implications, particularly in IELTS exams where accuracy and attention to detail are highly valued. Therefore, it is essential for test-takers to be aware of the differences and consistently use one spelling throughout their written and spoken responses.
To navigate this linguistic conundrum effectively, I advise my students to be mindful of the English variety they are studying and practice using the respective spelling consistently. This not only showcases their linguistic competence but also demonstrates their awareness of cultural and regional distinctions.
To summarize, the question of whether to spell this metallic element as “aluminum” or “aluminium” ultimately boils down to the differences between American and British English. Both spellings are correct, stemming from historical and cultural disparities. Therefore, it is crucial for IELTS test-takers to be cognizant of the preferred spelling in their target English variation and use it consistently in their exam preparations and responses.
