Bronze inscriptions	Small seal script	Transcribed ancient scripts

Pictogram (象形) ― a lit oil lamp. The derivative 煌 (OC *ɡʷaːŋ) refers to the original word.

Later developed into a phono-semantic compound (形聲／形声, OC *ɡʷaːŋ) : semantic 白 (“flame”) + phonetic 王 (OC *ɢʷaŋ, *ɢʷaŋs).

Bodman (1980) proposes a connection with 王 (OC *ɢʷaŋ) "king" (see there for more information).

/sume/ → /sube/

From Old Japanese, as a shift from older sume.[1]

Previously thought to be derived as the 連用形 (ren'yōkei, stem or continuative form) of Old Japanese verb 統ぶ (subu), modern 統べる (suberu, “to control, to govern, to rule”). However, later research into ancient phonetic spellings clarified that the be portion of the verb was realized as ⟨be₂⟩. During the Old Japanese stage, ⟨be₂⟩ could only have derived phonetically from ⟨me₂⟩, and not from the ⟨me₁⟩ syllable of the noun.[1]
