Dead Metaphors

A dead metaphor (also called a frozen metaphor or historical metaphor) is a figure of speech whose original imagery has been lost — either through extensive use or because the practice it references has become obsolete. Speakers use the phrase with its figurative meaning without awareness of the underlying comparison. Common examples: 'hands of a clock' (clocks no longer have literal hands), 'foot of the mountain,' 'falling in love,' 'groundbreaking' (originally from construction), and Origin of the Phrase 'Laundry List' (from the practice of inventorying clothes sent to professional laundry services). The concept has deep roots in rhetoric, but George Lakoff and Mark Johnson challenged it in *Metaphors We Live By* (1980). Their conceptual metaphor theory argues that so-called 'dead' metaphors are not truly dead — they continue to actively structure how we think, even when we do not notice them. For example, 'spending time' treats time as money, and this metaphor shapes real behavior and economic reasoning. Colin Murray Turbayne explored how dead metaphors shape scientific thinking in *The Myth of Metaphor* (1962). The debate between the traditional view (dead metaphors lose metaphorical force) and the cognitive linguistics view (conventional metaphors remain cognitively active) remains ongoing in the study of language and thought.
