the word 'unfurnished' is a layered construction in english. its core, 'furnish', entered middle english from old french furnir, meaning "to equip or provide", which itself has germanic roots. the prefix 'un-', a native english element from old english, is added to reverse the meaning, creating the sense of "not provided". the suffix '-ed' is then attached to form a participial adjective describing the resultant state. thus, the literal progression from "to provide" to "provided" to "not provided" perfectly captures the modern meaning of a space lacking furniture or an agreement lacking specific details.
