Etymology : Desuetude must be closely related to disuse, right? Wrong. Despite the similarities between them, desuetude and disuse derive from two different Latin verbs. Desuetude comes from suescere, a word that means “to become accustomed” (suescere also gave us the word custom). Disuse descends from uti, which means “to use.” (That Latin word also gave us use and utility.) Although less common, desuetude hasn’t fallen into desuetude yet, and it was put to good use in the past, as in the 17th-century writings of Scottish Quaker Robert Barclay, who wrote, “The weighty Truths of God were neglected, and, as it were, went into Desuetude.”
