Etymology: "Feithfulnesse" is a Middle English spelling of "faithfulness," and the "feith" spelling shows the word's path through Old French. The root is Latin "fidelis," meaning "faithful," from "fides," meaning "faith" or "trust." That Latin noun reached English through Old French "feid" or "feit," which is why medieval writers spelled the first syllable "feith" rather than the Latin-looking "fai-" of modern "faith." The word itself is built from an English base, "faithful," plus the suffix "-ness," which Old English used to turn adjectives into nouns of state or quality. So "faithfulness" literally means "the state of being full of faith." The "-ful" in "faithful" meant "full of," as in "sorrowful" or "hopeful," and the "-ness" added the abstract noun sense, creating a word for the quality itself. Medieval English spelling was unsettled, so the "-esse" ending in this form is an orthographic variant rather than a separate suffix. The modern spelling settled in the centuries after Middle English, though the exact dating of this form should be checked in the Middle English Dictionary before being relied on.
