inn-to-inn

The term is a modern compound, originating in the late 20th century within the context of recreational travel and tourism. It is constructed from the Old English word 'inn', meaning a public house or lodging for travelers, repeated with the preposition 'to' to indicate a progression from one point to the next. The logic is entirely transparent and descriptive, directly modeling the activity it names: a journey structured around moving from one inn to another. Unlike classical compounds with opaque roots, its meaning is immediately accessible from its constituent English words, reflecting its purpose as a practical label for a specific type of itinerary.

This is a compound adjective formed from the full phrase "inn to inn". It is not segmentable into smaller, independent morphemes without losing its idiomatic meaning.
