Etymology: Accustomedness is a plain compound: the adjective "accustomed" with the suffix "-ness" attached, which English has used since Old English to turn adjectives into nouns for a state or quality. The base itself comes from "accustom," a verb formed in Middle English from "custom" with the prefix "a-" and a verb-forming ending, meaning to make familiar through repeated habit. The "-ed" in "accustomed" is an ending that, in English, marks a word built from a verb's past form and then used as an adjective. The suffix "-ness" traces back through Middle English "-nesse" to Old English "-nes," which in turn descends from a Germanic root shared with many other abstract nouns. Put together, the word means the condition of having become used to something.
