The standard CC-CEDICT form for 'Edward' is
爱德华 (Àidéhuá, three characters).
爱德华德 is a four-character variant occasionally used in subtitles to mark the final '-d' or '-ds' of 'Edward(s)' more clearly. The same final
德 echoes the second character — translators reach for it because
德 (dé, virtue) reads neutrally and sounds close to English '-d'.
