Ancient simplification of 靁, which was a phono-semantic compound (形聲／形声, OC *ruːl) : semantic 雨 (“rain”) + phonetic 畾 (OC *ruːl).

The Northern Min initial s- may be due to the loss of a pre-initial which might have been a velar considering dialect forms in Henan, Hebei and Shanxi, e.g. Taiyuan Jin 忽雷 (hueh4 lui1) (Schuessler, 2007).

Perhaps from Sino-Tibetan. Compare Mizo râwl (“voice; cry (of an animal); sound”), Tibetan ཁྲོལ (khrol).

"spoiler"

Clipping of 捏他八雷 (niētābāléi), from Japanese ネタバレ (netabare).

"loyalty"

By homophony of 二 (ji⁶, “two”) and 義／义 (ji⁶, “spirit of loyalty”).
