Etymology
The word 'lungful' is a transparent Modern English compound, formed by directly combining the noun 'lung' with the quantifying suffix '-ful'. The Old English root for 'lung', lungen, is thought to be related to the concept of lightness, as lungs are light, air-filled organs. The suffix '-ful' originates from the Old English adjective full, meaning "full," and was grammaticalized to create nouns indicating a container's capacity or a specific quantity. Thus, 'lungful' logically denotes the specific quantity—the volume of air—that fills one's lungs in a single inhalation.
