higher-income

The compound adjective "higher-income" is a modern formation built from native English elements. Its first component, "higher," is the comparative form of "high," a word with ancient Proto-Germanic roots (hauhaz) conveying literal and figurative elevation. The second component, "income," entered English in the Middle English period, combining the preposition "in" with the noun "come" to logically mean "that which comes in," specifically money. The fusion of these parts creates a transparent, comparative descriptor that literally means "having money that comes in at a more elevated level," directly linking the concept of greater physical or social height to greater financial resources.

Structure: high (elevated) + er (comparative suffix) + income (money received) - high: From Old English hēah, of Germanic origin, meaning "of great vertical extent." Functions as the base adjective. - er: From Old English -ra, a comparative suffix used to form the comparative degree of adjectives and adverbs. - income: From Middle English income, from the phrase in (into) + come (arrival). Functions as a noun meaning "money received."
