Definition

Noun: A word that has multiple distinct meanings or senses. This is a core concept in semantics and lexicography, describing the common phenomenon where a single word form is associated with several related but different definitions.

Usage and Examples

A polysemous word is a lexical item with several meanings. These meanings are often historically connected but have diverged in usage.

• The word "bank" is a classic example of a polysemous word, as it can mean the side of a river or a financial institution.
• Lexicographers must carefully separate the different senses of a polysemous word in a dictionary entry.
• "Head" is a highly polysemous word, with meanings including a body part, the leader of an organization, and the top part of something.

Advanced Usage and Concepts

• Polysemy vs. Homonymy: Polysemy involves one word with multiple related meanings (e.g., "foot" of a person, "foot" of a mountain). Homonymy involves words that share the same form but have completely unrelated origins and meanings (e.g., "bat" (flying mammal) and "bat" (sports equipment)). A polysemous word exhibits the former.
• Sense Relations: The meanings within a polysemous word often form a network, connected by metaphor, metonymy, or specialization of meaning.

Variants and Related Words
