燈燎（遼鳥遼銚二反銚亭曜反考聲輕燒也字書云廷燭曰燎說文放火也從火尞聲也尞力召反尞字正體從火從昚作𤊽昚古慎字也焚柴燎天敬慎之至所以從昚從火也）。

燈燎 (lamps and torches): 燎 has two fanqie readings: *liáo* (遼鳥反 [leǔ]) and *liào* (遼銚反 [leuᴴ]; 銚 is pronounced *yào*, 亭曜反 [jeuᴴ]). The *Kaosheng* says: "To burn lightly." The character dictionaries say: "A courtyard torch is called 燎." The *Shuowen* says: "To set fire to; it takes the fire radical with 尞 (*liào*, 力召反 [leuᴴ]) as its phonetic. The orthodox form of the character 尞 takes fire and 昚, written as 𤊽; 昚 is the ancient character for 慎 (careful/reverent). Burning firewood to sacrifice to Heaven was the pinnacle of reverence and caution, which is why it takes 昚 and 火."
