earned-income

The term 'earned-income' is a modern legal and financial compound that precisely distinguishes the source of revenue. Its first element, 'earned', originates from the Old English concept of laboring to gain a reward or desert. The second element, 'income', has a more general origin, evolving from the literal Old English idea of 'a coming in' to specifically denote money received. The compound logic is transparent: it is income that one has actively worked for and thus 'earned', as opposed to passive investment returns or inheritances. This distinction is crucial in tax codes and economic discussions, carving out a specific semantic category from the broader concept of 'income'.

Structure: earned (past participle of 'earn') + income (money received) earned: From Old English 'earnian' (to earn, deserve, labor for), of Germanic origin. In this compound, it functions as a past participle adjective modifying the noun 'income'. income: From Middle English 'income' (entrance, arrival, a coming in), from Old English 'incuman' (to come in). The modern financial sense developed from the notion of money 'coming in'. It functions as the head noun in the compound.
