What does heftiness mean?
Heftiness is the noun that names the quality of being hefty. Most literally, it refers to considerable weight or bulk: the heftiness of a cast-iron pan or a rough-hewn timber beam can make it awkward or tiring to handle. In figurative contexts, heftiness can describe the force, importance, or substance of an argument, performance, or piece of writing. The word is uncommon compared with its relatives “heft” and “hefty,” but it is useful because it turns an adjective into a formal-sounding noun and focuses attention on a particular quality. It generally sounds neutral to formal, with a slight implication of solidity or authority. Although the plural “heftinesses” is grammatically possible, the noun is normally used as an uncountable mass noun, especially when discussing physical weight.
