Etymology
The compound adjective "seven-room" is a modern English formation following the productive pattern of number-noun compounding used to specify quantity. The first element, "seven," descends from an ancient and stable numeral, Proto-Indo-European septḿ̥, which is preserved across many Indo-European languages. The second element, "room," originates from a Germanic root conveying the concept of open or free space, which narrowed in meaning to designate an enclosed area within a structure. The logical combination is transparent: the numeral quantifies the noun, directly describing a property's key feature by counting its constituent spatial units.
