Definition

Meaning

To visit or pass by a place, especially by chance and usually without a specific plan or appointment.

To casually or unexpectedly arrive at or visit a location, often with a sense of serendipity; used primarily in literal spatial contexts and often implies being in the general vicinity or dropping in briefly.

Linguistics

Semantic Notes

Implies a lack of prior arrangement; strongly linked to chance and informal social interaction. Typically used with human subjects or mobile entities. The preposition 'by' is integral to the phrasal verb's meaning; substituting it with other prepositions changes the meaning.
