In a manner that increases in speed or intensity; with accelerating motion.
From accelerating (present participle of accelerate) + -ly. The root accelerate derives from Latin accelerare (to hasten), composed of ad- (to) + celer (swift).
The -ingly suffix on present participles is rare and creates an almost poetic quality—'acceleratingly' suggests continuous, mounting speed rather than a fixed fast pace, making it perfect for describing dramatic moments in storytelling!
