affordability

The word 'affordability' is a modern English formation, constructed by appending the noun-forming suffix '-ability' to the verb 'afford'. The core verb 'afford' originates from Old English 'geforthian', meaning "to carry out, accomplish," which itself is built from 'forth', implying progression or advancement. Over centuries, its meaning shifted from the general sense of "to manage" to the specific financial sense of "to have the means for." The suffix '-ability', derived from Latin '-abilitas', systematically converts verbs into abstract nouns denoting a state or capacity. Thus, 'affordability' literally translates to "the state of being able to afford," elegantly capturing the concept of financial accessibility as a measurable quality.

Structure: afford + ability afford: From Middle English 'aforthien', from Old English 'geforthian' ("to further, accomplish"), with the prefix 'a-' (intensive) + 'forthian' ("to further"). The modern sense of "have enough money to pay for" developed in the late 14th century. ability: From Middle English 'abilite', from Old French 'ablete', from Latin 'habilitās' ("aptitude, ability"), from 'habilis' ("easily handled, apt").
