Selected source glosses provide context, not a complete modern definition inventory

From Middle English faith (also fay), borrowed from Old French fei, feid, from Latin fidem. Doublet of foy. Displaced native Old English ġelēafa, which was also a word for belief. * Old French had [θ] as a final devoiced allophone of /ð/ from lenited Latin /d/; this eventually fell silent in the 12th century. The -th of the Middle English forms is most straightforwardly accounted for as a direct borrowing of a French [θ]. However, it has also been seen as arising from alteration of a French form with -d under influence of English abstract nouns in the suffix -th (e.g., truth, ruth, health, etc.), or as a recharacterization of a French form like fay, fey, fei with the same suffix. Compare Champenois fiate, fiaite, showing the same preservation of the final consonant.

Where this record stops

This page does not supply an independently verified sound-change sequence, first-use manuscript or complete family tree unless a cited analysis explicitly establishes one. Missing detail here is a limit of this record—not a claim that humanity knows nothing more.

An older meaning does not determine what a word must mean today. Follow the sources, preserve disagreements, and keep ancestry separate from interpretation.
