Synecdoche

The term traces to ancient Greek συνεκδοχή (sunekdokhē), meaning "simultaneous understanding," built from roots for "together," "out of," and "receive." Quintilian gave it its most influential early definition in the Institutio Oratoria (c. 95 CE), explaining it lets a listener "understand many things from one." The word entered English in the late 15th century via Medieval Latin, and 20th-century theorist Kenneth Burke later ranked synecdoche as one of his four master tropes of rhetoric.
