Etymology: "Roomful" is about as plain as English compounds get: "room" joined to the suffix "-ful", which turns a noun into a word meaning as much as the noun can hold. A "spoonful" is what a spoon holds, and a "roomful" is what a room holds. The suffix has been used this way since Old English, where "-full" was a full word meaning "full," and it was attached to nouns to express a quantity that fills a container. The noun "room" itself is much older, and its meaning has shifted over time. In Old English "rum" meant "space" or "an open area," a sense that survives in phrases like "elbow room." The sense of a partitioned chamber inside a building developed later, so "roomful" carries the idea of space first and walls second. Its exact date of first recorded use is not something I can confirm.
