Simply put, I am looking to find out if there exists a term for words or phrases that we have commonly accepted connotations for, despite whether or not context exists of its definition or origin.
For example:
- Breaking news: Most people probably cannot correctly identify the exact origin or official definition for this phrase; despite this, we all can understand it to mean a piece of information that is fresh and typically holds significance.
- Classifieds (Adverts): Classifieds, in relation to adverts, is one that I find most fascinating. The large majority of people you may ask will think of social classes (work) or soliciting classified information, as most of us, especially in the day of online newspapers, are more familiar with a different meaning of the word classified.
- Break a leg!: The most weak of any of what I could mention, though popular; consequently, hyperbole is not what I am seeking here. The Vaudeville origins may not be well known, however almost all people do not take this phrase literally - rather, we know it to be a call to good luck.
I do hope this question makes some sense.
