德尔 (Dé'ěr) is a common 2-character transliteration unit covering English 'Del-/Der-/Dell' as a name fragment: e.g.
德尔加多 (Delgado),
德尔塔 (Delta),
德尔马 (Del Mar). The standard transliteration of the Dell computer brand uses
戴尔 instead. Note the apostrophe in pinyin (Dé'ěr) marks the syllable boundary before
尔.
