the adjective 'hefty' is a relatively modern english formation, emerging in the mid-19th century. it derives directly from the noun 'heft', meaning weight or heaviness, which itself originates from the verb 'heave', a word of old english and proto-germanic ancestry related to lifting. the suffix '-y' is a common english adjectival ending, turning the concrete noun into a descriptive term. thus, the literal sense of 'having heft' evolved from describing physical weight and bulk to also signify substantial amounts, particularly of money, capturing the idea of something impressively large or considerable.

the word is a simplex form derived from the noun 'heft' with the addition of the adjectival suffix '-y'. 'heft' itself is of germanic origin, related to 'heave'.
