What does passersby mean?
Passersby is the standard plural of passer-by, meaning people who move past a particular place, often on foot. It is especially common in descriptions of streets, parks, buildings, shops, and public spaces, where people may be passing without interacting with one another or with the location itself. For example, a report might say that passersby gathered, watched, or offered assistance. The word is neutral in tone and can suggest the ordinary movement of people through a place, sometimes creating a sense of anonymity or a shared public setting. Unlike bystanders or onlookers, passersby do not necessarily stop to observe what is happening. The singular form is passer-by, while passersby is used for more than one person. Although the plural can be written as one word in standard modern usage, hyphenated forms such as passers-by also occur in older or stylistic contexts.

Where does passersby come from?
The compound passer-by was formed in English from passer, an agent noun derived from pass, and the preposition by. The element pass comes ultimately from Latin passare, meaning “to step” or “to pass,” while by comes from Old English bī, meaning “beside” or “near.” The plural passersby developed as the usual unhyphenated form, with passers-by remaining a less common hyphenated variant.
