Literary device

Purposeful use of language

A literary device, literary technique, figure of speech, rhetorical device, stylistic device, or trope is any strategy of using language that a writer or speaker employs to deliberately achieve some purpose. This purpose is typically: to focus or guide the audience's attention, to make the language or its content memorable, or to evoke a particular emotional, rational, aesthetic, or other response. The many names (or synonyms) for this concept may carry slightly distinct meanings in technical scholarly usage.
