Past Tense of “beget”
The past tense of beget is begot (begat in archaic/biblical use); the past participle is begotten.
Why “beget” behaves this way
"Beget" descends from Old English "begietan," a compound of "be-" plus "gietan" (to get, to obtain), making it a close historical cousin of the modern verb "get" — both ultimately share the same Germanic root, though "get" itself was later reinforced and reshaped by the Old Norse "geta" during the Viking settlement period discussed on that page, while "beget" kept a more conservative, native English shape.
"Begat," the form most modern readers recognize from the King James Bible's genealogies ("Abraham begat Isaac"), is an older, now archaic simple past that has been almost entirely replaced by "begot" in every context outside deliberately biblical or archaic-styled writing — a rare case where a once-standard verb form survives today almost exclusively because of a single famous historical text. The verb's narrow modern survival contrasts sharply with its Old English frequency, when "begietan" covered ordinary getting and obtaining alongside its more specialized sense of fathering offspring, a much broader everyday role than the narrow, elevated niche it occupies in English today.
The common confusion
The confusion is almost entirely about register: "begat" reads as instantly, deliberately archaic or biblical to modern readers, while "begot" is the expected simple past in any contemporary formal or literary sentence, and mixing the two within otherwise modern prose creates a jarring, inconsistent tone.
How it's actually used
"Beget" survives today almost entirely in formal, literary, or rhetorical writing describing abstract cause and effect — "violence begets violence," "poverty begets crime" — a figurative use far more common in modern English than the verb's original literal sense of fathering a child, which now reads as distinctly archaic or biblical outside historical or religious contexts. The cause-and-effect proverb structure ("X begets Y") is a recognizable rhetorical pattern borrowed by writers wanting a slightly elevated, aphoristic tone, precisely because the verb's biblical association lends any sentence a weightier, more timeless feel than a plainer verb like "causes" or "leads to" would. Genealogical and historical writing about royal lineages still occasionally uses "begat" deliberately for stylistic effect, echoing the King James Bible's cadence even when describing entirely secular family trees, a conscious borrowing of register rather than an accident.
Across the tense system
"Begotten" survives in one especially famous fixed theological phrase, "only begotten son," from traditional English Bible translations and creeds, a use so specific and formulaic that most modern speakers would never otherwise reach for this participle in ordinary writing.
Common real mistakes
The most common mistake is using "begat" in otherwise modern, non-biblical prose, where it reads as an odd stylistic inconsistency rather than a deliberate archaism. A separate, rarer error is treating "beget" as a fully ordinary transitive verb describing literal parenthood in contemporary writing, where a plainer, more natural verb like "father" or simply "have children" fits the modern register far better. A further subtlety many writers miss is that "beget" in its abstract, cause-and-effect sense ("poverty begets crime") functions best in short, aphoristic sentences; stretching it across a longer, more complex sentence structure tends to sound strained rather than naturally proverbial. A further slip is spelling "begot" as "begat" by simple confusion between the two archaic-sounding forms, without realizing that only "begat" carries the specific, deliberate biblical association while "begot" is the neutral modern default. A last usage note: because "beget" so rarely appears outside proverbs or historical text, many writers simply avoid it altogether rather than risk misjudging the register, opting instead for plainer verbs like "cause" or "lead to" in everyday formal writing.
Examples
- The war begot years of instability across the region.
- Ignorance has begotten countless conflicts throughout history.
- Poverty begets crime in far too many communities.
- Their negligence had begotten a crisis no one anticipated.
- One lie often begets another.
- Abraham begat Isaac, and Isaac begat Jacob. (archaic/biblical)
- Violence begets violence, as the saying goes.
- Such carelessness begets disaster sooner or later.
Memory trick
Remember "beget" as a formal cousin of "get," sharing the same ancient root, and reserve archaic "begat" strictly for deliberately biblical or historical-sounding writing — everywhere else, modern formal English expects "begot" as the simple past.
