艾奎拉 transliterates Aquila / Aguila. Aquila is also the Latin name of the constellation 天鹰座 (the Eagle), home of the bright star Altair (牛郎星). The Italian city L'Aquila and the singer Christina Aguilera (often 阿奎莱拉) share the same root.
memory
艾 ài ('A-') + 奎 kuí ('-qui-') + 拉 lā ('-la'). 奎 is rarely seen outside transliterations and the proper noun 奎宁 (quinine); it carries the 'kw-' sound that 'qu' makes in English.
