Retronyms
A retronym is a new name given to something old, coined because a newer version came along and the original word was no longer specific enough. Before electric guitars, a guitar was just a guitar; afterwards, people needed the word 'acoustic guitar'. The same thing happened to the landline, the paper book and the silent film.
This guide collects common retronyms grouped by theme - technology, everyday life, media and history - and explains the invention or change that made each new name necessary. Retronyms are a neat window into how quickly the world changes, and how language scrambles to keep up.
