maculation (n.)

late 15c., maculacioun, "sexual defilement, sinning," from Latin maculationem (nominative maculatio) "a spotting," noun of action from past-participle stem of maculare "to make spotted," from macula "spot, stain" (see macula). In English, the literal meaning "act of spotting, a staining with spots, state of being spotted, pattern of spots on a plant or animal" is by 1707. Nares, in his "Glossary" of Shakespeare's words (1822) calls it "an uncommon word, not so properly obsolete, as never thoroughly in use."
