Acquired synecdoche

Acquired synecdoche refers to a linguistic phenomenon where a part of something is used to represent the whole, or vice versa, based on common associations. For example, saying "the White House announced" refers not just to the building but to the U.S. presidential administration. In general knowledge, this shorthand helps convey complex ideas more efficiently, as people recognize the associated meanings. It often arises from cultural understanding, where certain parts become iconic representations of broader concepts, enhancing communication without lengthy explanations.
