Why the Past Tense is “Fell Down”
The reason we say “fell down” instead of “falled down” is that fall is an irregular verb.
Irregular verbs don’t follow the standard “add -ed” rule for past tense. Instead, they change their form entirely. The root verb “fall” changes its vowel sound — a process called ablaut — to become “fell” in the past tense.
Why this matters:
- “Fall down” is a phrasal verb, but the tense change happens in the main verb “fall,” not in the particle “down.”
- The same applies to analogous verbs like “sing–sang–sung” or “begin–began–begun.”
In other words, “fell down” is just the present tense “fall down” shifted to the past, with the irregular conjugation handled by “fall.”

Origin – Etymology of the Phrase “Fall Down”
The verb fall comes from the Old English “feallan,” meaning “to drop from a height, to come down, to die.”
- Proto-Germanic: fallaną (to fall)
- Old Norse: falla (to fall)
- Old High German: fallan
The down part is a directional adverb that reinforces the downward motion. In Old English, you’d find “feallan niþer” meaning “fall downwards.” Over time, “down” became a common intensifier with motion verbs, forming today’s “fall down.”
