A short transliteration that can stand for English 'Phil', 'Fer-' (as in Fernandes/Ferguson), or German 'Fehr'.
费 (fèi) renders the 'f' onset,
尔 (ěr) is the universal Chinese 'r/-r' ending used in transliterations like
哈利 (Harry) and
彼得 (Peter). When
费尔 prefixes more characters (
费尔南德斯 'Fernandes',
费尔普斯 'Phelps'), it becomes the start of a longer name.
