What does etymology study?

Etymology is the study of the origin or derivation of words. It delves into how words have evolved over time, tracing their roots back to earlier forms and languages. This field helps illuminate the history of language, revealing connections between words and their meanings across different cultures and periods. By understanding etymology, one can gain insight into the cultural and historical contexts that have shaped language, as well as how language influences thought and communication.

Examining the other options, the future development of words pertains more to linguistics and predictions about language evolution rather than etymology. The study of metaphors involves figurative language and the creative aspects of communication, which falls outside the scope of etymology. The art of writing encapsulates a broad range of skills, including the structure and style of written work, rather than focusing on the origins of words themselves.
