Faith is an English word that can be very easily mispronounced.
Faith is pronounced phonetically as "fay-th".
In Latin the word 'fides' means faith. Faith is defined as a strong belief and conviction. Faith was originally spelled 'feith', and its plural is still 'feiths' (with the long e) in Scotland. Faith is a virtue that many people refer to as being from the Latin term 'fides', which means faithful.
