"Eftsoon" (also "eftsoons") derives from Old English "eft" (again, afterward) combined with "soon," creating an adverb that signals immediate succession or recurrence. Spenser and other Renaissance poets employed this term extensively to maintain narrative momentum and archaic atmosphere in their verse. The word serves both temporal and rhythmic functions, indicating that an action follows quickly upon another while contributing to the musical flow of poetry. Its obsolete quality makes it particularly valuable for creating pseudo-medieval settings or evoking the romance tradition. Poets appreciated its flexibility—it could mean "soon," "again," "in return," or "afterward"—allowing contextual nuance while preserving an antique tone essential to works seeking to recreate or honor earlier literary periods.

Eftsoons appears most prominently in Spenser's The Faerie Queene and other deliberately archaic poetry, functioning as a narrative time marker meaning either "immediately" or "soon after," depending on context. The term combines "eft" (meaning "again" or "afterward," from Old English) with the adverbial "-s" and "soon," creating a deliberately medieval-sounding compound. Even in Spenser's time (late 16th century), eftsoons was recognized as artificially antique, part of his conscious effort to create a pseudo-Chaucerian style. Students should recognize that eftsoons serves dual temporal functions: it can indicate immediate action ("he eftsoons departed" = he immediately left) or subsequent action ("eftsoons he returned" = soon after, he returned). The context and narrative flow determine which meaning applies. By Shakespeare's era, the term was already considered archaic and rarely appeared outside of deliberately medievalizing works. Modern poets virtually never use eftsoons except when imitating Spenser or creating overtly archaic effects. The "-sons" ending relates to other archaic temporal adverbs like "betimes" and "whilom." Understanding eftsoons helps students recognize Spenser's characteristic archaizing technique and track narrative sequence in complex medieval-style allegories. Compare "anon" (soon, more commonly used) and "forthwith" (immediately, less archaic-sounding) for similar temporal concepts with different stylistic registers.

Eftsoon appears throughout medieval and Renaissance poetry indicating temporal sequence, particularly in narrative verse requiring frequent time markers. Chaucer, Spenser, and medieval romances employ it extensively. The term suggests both immediacy ("soon afterward") and repetition ("again"), making it versatile for narrative pacing. Related to "eft" (again) with intensifying "soon." Etymology from Old English "eft sona" (again soon). Essential for analyzing narrative temporal structures, especially in romance and epic where sequential action requires clear markers. The term's rhythmic qualities (two syllables, pleasing sound) made it poetically useful beyond mere temporal meaning. Useful for discussing how archaic texts manage time and sequence, and how deliberate archaism functions stylistically in later imitators like Spenser.
