gravy
Apparently gravy came to English as a result of a misspelling: the word goes back to the Latin granum, “grain, seed,” which made its way into Old French initially as grané, “sauce or stew,” possibly in the sense of being “properly grained, seasoned” with grain being used to mean “spice” in this instance. According to Etymonline, not only was the n misread as a u but also u was “used for v in medial positions in medieval manuscripts.” And the Old French grave, graue made its way into English under its current meaning as gravy in the 1300s. Wiktionary specifies that the word entered Middle English as gravy, greavie and gravy, “possibly from greaves, graves, “the sediment of melted tallow.”
