'adzooks' originates from the alteration of 'gadzooks', which is a contraction of 'God's hooks', referring to the nails used in the crucifixion of Jesus.

'adzooks' changed from the earlier form 'gadzooks', which was used as a mild oath or exclamation in the 17th century.

Initially, it meant 'by God's hooks', but over time it evolved into a general exclamation of surprise or amazement.
