Derived from “amain” (itself from Old French “à main,” meaning with might), “amainly” modifies action with urgency and power. Though rare, it appears in poetic descriptions of storms, battles, or passionate emotion, where its energetic adverbial form enhances rhythm and intensity. Its obsolescence adds historical flavor while preserving the kinetic drive of older verse styles.

“Amainly” is an adverbial intensification of “amain” (with might or speed), derived from Old French “à main.” It describes action executed swiftly, forcefully, or with vigor—galloping horses, rushing winds, or passionate declarations. Though rare, it appears in 16th- and 17th-century verse to heighten kinetic energy in battle scenes, storms, or emotional outbursts. Its three-syllable structure (a-MAIN-ly) fits anapestic or dactylic meters well. Poets may choose it over “quickly” or “fiercely” to preserve period diction or add sonic weight through its emphatic stress pattern. Related adverbs include “full amain” and “right amain,” both emphasizing immediacy and power.
