1. "All hands on deck" is an example of synecdoche, where 'hands' represent the whole person.
2. "The press was in a frenzy" is another synecdoche, with 'press' referring to journalists.
3. "The city came out to cheer the team" uses synecdoche with 'city' standing in for the residents.
4. "He's got a new set of wheels" is a synecdoche with 'wheels' representing a car.

Synecdoche is a type of metonymy

I just had this question in school. It is false, Synecdoche is not a type of irony.

The cast of Synecdoche - 2011 includes: Keith David

In "The Catcher in the Rye," the red hunting hat is a symbol of individuality and independence, while Holden Caulfield's obsession with rescuing children from falling off a cliff represents his desire to protect innocence and childhood. These examples of synecdoche help to convey larger themes of alienation, loss, and the struggle for identity in the novel.
