Americans dutifully adopted the new term, but many British users disliked aluminum, pointing out that it disrupted the -ium pattern established by sodium, calcium, and strontium, so they added a vowel and syllable.

美国人则完完全全地接受了这个新术语,但很多英国却不喜欢aluminum这个名字,指出其破坏了由sodium, calcium, and strontium建立起的-ium的形式,因此他们在aluminum的基础上加了一个元音和一个音节。
