Usage notes

The inflected forms bade, bad, and bidden are archaic. They remain in marginal use, particularly regarding greetings, as in “bade farewell”, but uninflected bid is significantly more common, and bidden is especially rare.^[1]

When it does occur, it is usually in an elevated, ironical or metaphorical style e.g "I have bidden farewell to my prospects of promotion."

When bade or bad is used in formal speech the pronunciation /bæd/ may be heard. However, when a dated text is being read or recited (e.g. on stage, in school or in church etc.) /beɪd/ is quite usual.

1. (intransitive) To make an offer to pay or accept a certain price.

3. (intransitive) To make an attempt.
4. (transitive, intransitive, card games) To announce (one's goal), before starting play.
5. (obsolete) To proclaim (a bede, prayer); to pray.
