Here are some examples:
* Manufactory: A place where things are made by hand.
* Manual: A book of instructions.
* Manicure: The care and treatment of the hands and fingernails.
* Manipulation: The act of controlling or influencing something with the hands.
However, other prefixes can be used depending on the context, such as:
* Chiro-: Derived from the Greek word for "hand," this prefix often indicates a relationship to the hand, like in chiropractic.
* Dextr-: Meaning "right," this prefix can be used when referring to the right hand, such as in dexterous.
The best prefix to use will depend on the specific word you're trying to create.
