Oath in British Sign Language (BSL)
The sign for “oath” in British Sign Language represents a solemn promise or declaration, often used in legal contexts or when making serious commitments. This sign is commonly used in the UK Deaf community when discussing legal matters, ceremonies, or personal vows.
How to Sign “Oath”

- Begin with your dominant hand in a flat shape (like a “B” handshape) held in front of your chest.
- Raise your hand slightly while turning it outward to face away from you, indicating the seriousness of the promise.
- With a firm expression, nod your head slightly to emphasize the importance of the oath.
- Hold this position for a moment to convey the weight of the promise being made.
Common Mistakes
- Forgetting to use facial expressions; non-manual features are essential for conveying the significance of the sign.
- Using a loose handshape instead of the flat “B” handshape, which can change the sign’s meaning.
- Not maintaining eye contact, which is important in BSL for engaging with the audience and showing sincerity.
