Past Tense of “befall”
The past tense of befall is befell; the past participle is befallen.
Why “befall” behaves this way
"Befall" descends from Old English "befeallan," a compound of "be-" plus "feallan" (to fall) — sharing its entire ablaut pattern with modern "fall" (fall/fell/fallen), just with the intensifying prefix "be-" attached, the same way "become" attaches "be-" to "come." Historically the prefix broadened the verb's meaning from a literal physical fall to a more abstract sense of something happening to or descending upon someone, a shift that had already occurred by the time of the earliest Old English texts.
"Befall" is now almost entirely restricted to formal, literary, or slightly archaic registers describing misfortune specifically — a tragedy, a disaster, or a strange event "befalls" someone — and it has essentially never been used for positive events in standard modern usage, a narrowing of tone that its base verb "fall" doesn't share, since "fall" itself remains neutral about whether the falling is good or bad. Fairy tales translated into English, particularly from German and French sources in the 18th and 19th centuries, relied heavily on "befall" to introduce a story's central misfortune, cementing the verb's strong association with narrative doom that persists in modern usage today.
The common confusion
There's little confusion over the conjugation, which mirrors "fall" exactly; the real usage point is that "befall" almost always appears in an impersonal, subjectless-feeling construction with an indirect object ("whatever befalls us," "a tragedy befell the town"), and using it with an ordinary direct subject performing an action (rather than something happening to someone) sounds distinctly wrong to native ears.
How it's actually used
"Befall" survives today mainly in formal narrative writing, fairy tales, news reporting on disasters, and legal or insurance language describing unforeseen misfortune ("should any accident befall the policyholder"), giving it a noticeably more elevated register than everyday alternatives like "happen to" or "occur to." The word rarely appears in ordinary spoken conversation at all, which is part of why it can sound theatrical or overly formal if used casually about a minor inconvenience rather than genuine misfortune. Insurance policies specifically use "befall" in boilerplate clauses about unforeseen accidents ("should any injury befall the insured party"), a deliberately formal, slightly old-fashioned legal register chosen precisely because it sounds more solemn and precise than a plainer everyday phrase would.
Across the tense system
"Befallen" in the present perfect ("no harm has befallen them") is common in reassuring or reporting contexts confirming an absence of misfortune so far, while the simple past "befell" typically narrates a specific completed misfortune within a story or historical account, a distinction in narrative function rather than strict grammar.
Common real mistakes
Because the verb is rare in everyday speech, the most common issue is a mismatch of register — deploying "befall" in a casual context where it reads as overly dramatic or old-fashioned for the situation described. A genuine grammatical error some learners make is treating "befall" as an ordinary transitive verb with the misfortune as subject and the person as object in the wrong order ("they befell a tragedy" instead of the correct "a tragedy befell them"), since the misfortune must be the grammatical subject. A further register mismatch occurs when writers use "befall" for a merely inconvenient or minor event rather than genuine misfortune, since the word's weight doesn't suit small, everyday annoyances. Finally, writers occasionally pair "befall" with an overly trivial subject ("a small inconvenience befell her"), a mismatch of weighty verb and minor event that undercuts the deliberately serious tone the word is meant to carry.
Examples
- A great misfortune befell the small village that winter.
- No harm has befallen the travelers so far.
- Whatever befalls us, we'll face it together.
- Tragedy had befallen the family twice within a year.
- Such disasters rarely befall a community without warning.
- It befalls every generation to face its own challenges. (formal)
- Nothing so strange has ever befallen this town before.
- The same fate befalls anyone who ignores the warning.
Memory trick
Remember "befall" is "be-" plus "fall" with the identical fall/fell/fallen pattern, but restricted almost exclusively to misfortune happening to someone — if the sentence describes something good happening, reach for "happen to" or "come upon" instead, since "befall" carries a built-in note of doom.
