The word "埃文" is formed through a process of phonetic transliteration, specifically for representing foreign names or terms in Chinese. The two characters, "埃" (āi) and "文" (wén), were chosen primarily for how closely their combined pronunciation approximates the sound of the English name "Evan" or similar. This is a standard method where individual Chinese characters, which each carry their own inherent meanings, are used purely as phonetic building blocks to mimic foreign sounds. In this case, while the literal meanings of "dust" or "fine particle" for "埃" and "writing" or "culture" for "文" are irrelevant to the name's intended reference, the character "文" is often favorably selected in transliterations for its positive cultural connotations.
