【definitions】In any field of study, whether it be science, technology, philosophy, or everyday language, the term “definitions” plays a crucial role in clarifying meaning and ensuring effective communication. A definition is a statement that explains the meaning of a word, phrase, or concept. It serves as a foundation for understanding and discussion, helping to eliminate ambiguity and provide a common ground for interpretation.

While definitions can vary depending on context, they generally aim to capture the essential characteristics of a subject. Different types of definitions exist, each serving a specific purpose. Below is a summary of various types of definitions, along with their descriptions and examples.

Type of Definition	Description	Example
Lexical Definition	A definition that provides the standard meaning of a word as found in a dictionary.	"Cat" – a small domesticated carnivorous mammal.
Stipulative Definition	A definition that assigns a specific meaning to a term for a particular purpose, often in academic or technical contexts.	"A 'smartphone' is defined as a mobile phone that has advanced computing capabilities."
Ostensive Definition	A definition that uses direct demonstration or pointing to an object to convey meaning.	Showing a cat and saying "This is a cat."
Operational Definition	A definition that specifies how a concept is measured or observed in an experiment.	"Intelligence is defined as the score obtained on a standardized IQ test."
