Passerbys vs. Passersby – Which is Correct?
The correct plural form of the noun “passerby” is passersby. The spelling “passerbys” is incorrect and a common grammatical error. This mistake often arises from applying standard pluralization rules to compound nouns, where the primary noun (“passer”) should be pluralized, not the modifying word (“by”).
Passerbys or Passersby – Which is Correct?
Between “passerbys” and “passersby,” only passersby is the grammatically correct plural form. The word “passerby” is a compound noun, meaning someone who passes by. When pluralizing compound nouns formed with a noun followed by a preposition or adverb, the plural ‘s’ is added to the noun component, not the entire phrase. Therefore, “passer” becomes “passers,” leading to “passersby.” The incorrect “passerbys” is a phonetic confusion, where the ‘s’ is mistakenly appended to the end of the entire word.
The Best Trick to Remember the Difference
To remember the correct form, focus on the core noun within “passerby”—it’s the “passer.” Think of it as “one who passes by.” When you want to refer to multiple people who pass by, you make the “passer” plural: “passers.” The “by” remains unchanged. So, it’s “passers by,” which is written as one word: passersby. If you wouldn’t say “runners up” as “runner ups,” you shouldn’t say “passersby” as “passerbys.”

|---|---|---|---|
| passersby | Plural Noun | People who pass by, especially by chance. | The unusual sight attracted the attention of many passersby. |
| passerbys | Incorrect | Incorrect spelling of the plural form. | (Incorrect) Many passerbys stopped to watch. |

Etymology of the word Passersby
The word “passerby” originated in the late 17th century. It is a compound noun formed from the verb “pass” and the preposition “by.” The singular “passerby” literally means “one who passes by.” The plural “passersby” follows the rule for pluralizing compound nouns where the main noun (“passer”) receives the plural ‘s’, a pattern also seen in words like “mothers-in-law” or “attorneys general.”
Related Concepts
Understanding the rules for pluralizing compound nouns helps clarify why “passersby” is correct and “passerbys” is not.
- Compound Nouns: These are nouns made up of two or more words, often acting as a single concept. They can be written as one word (e.g., “toothbrush”), hyphenated (e.g., “mother-in-law”), or separate words (e.g., “attorney general”). When pluralizing compound nouns, the ‘s’ is typically added to the main noun within the compound, not necessarily at the very end of the entire phrase.
- Pluralization Rules: While most English nouns form their plural by adding ‘-s’ or ‘-es’ to the end, compound nouns often have specific rules. For compound nouns like “passerby” (noun + adverb/preposition), the noun component (“passer”) is pluralized.
