The word rumble originates from Middle English romblen, likely imitative of the low, rolling sound it describes (onomatopoeic). The suffix -ing transforms the verb into a noun or present participle, emphasizing ongoing action or state. The morpheme rumble itself is indivisible in modern English, preserving its sonic association with low-frequency noise.
