塞克斯 transliterates Western surnames Sykes / Sachs / Saxe / Sax. Pattern:
塞 (Sai, 'Sy-/Sa-') +
克 (ke, '-ke') +
斯 ('-s'). Note: the unrelated English noun 'sex' is rendered
性 (xìng) in Chinese, never
塞克斯.
塞 here is read sài; the same character also reads sāi ('to stuff') and sài ('strategic pass') — this transliteration uses sài.
