# Definition:Word (Natural Language)

## Definition

A word in natural language is intuitively understood as a sequence of sounds which expresses a concept.

When written down, it appears as a sequence of letters, each one of which either is, or contributes to, a phoneme.

## Also known as

A word in this context is sometimes referred to as a phonogram, indicating that it is a representation of a sequence of sounds.

Compare this to ideogram, which is a symbol which stands for a concept directly.
