Passerbyers or Passersby or Passerby: The Correct Forms Explained
Let’s cut through the confusion immediately:
The correct singular form is “passerby.”
The correct plural form is “passersby.”
“Passerbyers” is NOT a correct word in standard English. It is a common error arising from attempting to pluralize an already pluralized form.
Why “Passersby” Is the Correct Plural
The word “passerby” is a compound noun made up of the verb “pass” and the adverb “by.” The person is one who “passes by.” When pluralizing compound nouns that consist of a noun plus a modifier, English often pluralizes the noun part . Therefore:
- Passerby = one who passes by
- Passersby = multiple people who pass by
This rule applies to other compound nouns as well:
- “Mother-in-law” → “mothers-in-law”
- “Attorney general” → “attorneys general”
- “Court martial” → “courts martial”
Why “Passerbyers” Is Incorrect
“Passerbyers” incorrectly treats the entire word “passerby” as a single unit and adds “-ers” to the end. This would be like saying “mother-in-laws” instead of “mothers-in-law”—it disregards the internal structure of the compound word.
A common mistake to avoid:
- ❌ “The passerbyers stopped to watch the street performer.”
- ✅ “The passersby stopped to watch the street performer.”
Quick Reference: Three Forms at a Glance

FAQs
1. Why is “passerbyers” incorrect?
“Passerbyers” incorrectly pluralizes an already pluralized compound word. “Passerby” consists of “passer” (one who passes) and “by.” The correct plural is “passersby” because the noun part “passer” becomes “passers.” “Passerbyers” treats the whole word as a single unit, which violates English compound noun pluralization rules.
2. Is “passer-bys” ever acceptable?
No. While hyphenated forms exist (“passer-by” and “passers-by”), the “s” must be attached to “passer” or “passers,” not to “by.” Therefore, “passer-bys” is incorrect. The correct hyphenated forms are “passer-by” (singular) and “passers-by” (plural).
3. How do I remember the correct plural form?
Think of “passerby” as “one who passes by.” For multiple people, it’s “people who pass by” → “passersby.” Another memory aid: you wouldn’t say “mother-in-laws” (correct: “mothers-in-law”), so don’t say “passerbyers” (correct: “passersby”).
4. Is “passerby” formal or informal language?
“Passerby” is neutral—it works in both formal and informal contexts. In legal writing, you might see “passerby” in witness statements. In creative writing, it appears in poetry and prose, In journalism, it’s standard for describing eyewitnesses or crowd scenes. It’s not overly casual or overly formal.
5. What’s the difference between “passerby” and “bystander”?
A “passerby” is someone who passes by a place, often moving through. A “bystander” is someone who is present at an event but not necessarily passing through—they might be standing still. “Bystander” often implies witnessing something significant; “passerby” suggests transience and movement. All passersby could be bystanders if they stop, but not all bystanders are passersby.
