The Sifu comes from the Chinese word "師父" or "師傅"
Si(師) means "teacher" and fu(父) means father.

Sifu actually means someone who teaches you a kind of skills or techniques, which can be a kind of material arts, a kind of musical instruments, etc.

Sifu is not only your teacher, but also your father.

We have a idiom among us:
一日為師,終生為父
That means "If Sifu teaches you for one day, he is already your father for your whole life."

So we have to respect to our Sifu, just like we have to respect to our dad.

Similarly, SiGung (師公) is the Sifu of your Sifu,
Gung actually means "Grandfather" in Cantonese, and you got it.
Sifu taught me a lot yesterday.
This is my Sifu, Sifu Leung.

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.
