Graphical notes

 * In certain modern romanization of Nôm texts where this morpheme was written with, , and , it is sometimes transcribed as ⟨cong⟩ or ⟨cung⟩. This is due to the misinterpretation of the nature of the graphemes: the phonological (and likely also phonetic) value of the morpheme that these graphemes represented at the time when they were first used was probably (or something similar) and was the ancestor of modern trong, with the medial liquid maintained until at least the end of the Middle Vietnamese period. For a similar case, compare modern ,  < , used to be spelled with  in numerous Nôm texts. The *cong and *cung romanizations are thus nothing more than ghosts, and ought to be transcripted instead as ⟨trong⟩ (if scriptor only tries to write the modern reflex) or reconstructed  (for historical value).
