# Likely from a merger of two Proto-Mongolic verbs: *seri- (“to wake up”) and *sere- (“to notice”), compare Buryat һэрихэ (herixe), Kalmyk серх (serx), Dongxiang xierei (“to wake up”). # The assumed Mongolic verb *sere- probably derives from Proto-Turkic *seŕ-, *sēŕ- (“to feel, understand”), compare Turkish sezmek.
