Final answer:
The origin of a word in a dictionary reveals its etymological background, showing how words evolve and change meaning over time. Examples such as 'elasticity' demonstrate the figurative origins of many terms, with dictionaries documenting these linguistic changes.
Step-by-step explanation:
In a dictionary, the origin of a word is typically indicated, providing information on its etymological background. This can involve detailing the initial concrete object or specific action a word once referred to. Over time, words evolve, taking on new meanings or nuances, with some falling out of use. Dictionaries, whether in print or electronic form, help track these changes, offering a snapshot of how language is used at different points in time. An interesting example is the investigation into the historical use of words through resources like the Oxford English Dictionary (OED), which can reveal surprising histories and origins. The word 'elasticity', for instance, can be traced back to verbs meaning "draw" or "drag," reflecting a rich tapestry of figurative language and metaphor inherent in linguistic evolution.
