1. be special or unique, or do something in a completely new or different way
a new approach to something which breaks the mold/mould
The expression 'to break the mold' or to 'break the mould' means to do something completely different from what has been done before, or from what is usually done. If you 'break the mold/mould' you change a situation completely and defy convention. It can also be used to refer to a special or unique person. For those reasons, the term is usually used in a positive sense to describe something or someone innovative, daring, and forward-thinking. Both spellings are acceptable, and it can be used in either a social or professional context.
