Nonsummativity refers to a phenomenon where by combining individual parts, the overall outcome or value is more than the sum of the parts. However, there are several synonyms to this term that can be used in various contexts. Some of the synonyms for nonsummativity include synergy, emergent properties, and holistic integration. Synergy refers to the effect of combining separate elements to create something greater. Emergent properties describe the unpredictable results from a combination of parts, where individual parts alone would not have produced the desired result. Holistic integration means the interaction of multiple elements to create a complete system. These terms can be used interchangeably depending on the context and the intended meaning.
