How to Sign “Natural Philosophy”

- Start with your dominant hand in a flat ‘5’ shape, palm facing forward, placed at your forehead.
- Move your hand outward and slightly upward in a circular motion, as if you are expanding your thoughts or ideas.
- Once your hand is fully extended, transition to a ‘P’ handshape with your palm facing down, and place it near your chest.
- For the ‘philosophy’ part, bring your ‘P’ handshape forward in a gentle forward motion, while maintaining a thoughtful facial expression.
- Ensure you use non-manual features by raising your eyebrows slightly during the motion to indicate a questioning or thoughtful tone.
Common Mistakes
One common mistake is forgetting to use the correct handshape for ‘philosophy’, leading to confusion. Another error is not incorporating facial expressions, which are essential in BSL for conveying meaning. A third mistake is using too much movement, which can distract from the sign’s clarity.
BSL vs ASL
In BSL, the sign for “natural philosophy” is distinctly different from ASL. While BSL relies more on facial expressions and the use of space for context, ASL may use a more direct handshape without the circular movement. This highlights the unique grammatical structures of both sign languages.
