Compare the obsolete/archaic compound bặt tin (“radio silent”).\nThe morpheme bặt is of particular interest; its modern \"standard\" Sino-Vietnamese reading is bạt with long vowel. This \"four-character compound\" is also attested as biệt vô âm tín; this \"alternation\" of the first morpheme is also seen in bặt tăm vs. biệt tăm, the latter form probably represents contamination by biệt (別, “to part, to leave”). Furthermore, some dictionaries (including Đại Nam Quấc âm tự vị (1895)) defines bặt as if it is a variant of bật, which is likely a native word; there was probably some more contamination involved.",
