Fide

Fide is a masculine noun in Latin-based or ecclesiastical contexts meaning faith or trust. In English-use, it appears chiefly in phrases like “fidei” or in technical terms borrowed from Latin, signifying belief, trust, or confidence. This term is uncommon in everyday English and is typically encountered in academic, legal, or religious discourse. The pronunciation is typically two syllables, with emphasis on the first syllable, and a smooth, closed-vowel ending.
