Some examples of article titles:
- Taking the Leap: How Sociolinguists Can Handle Divergence
- Closing the Gap: On Linguistic, Regional Convergence
- Linguistics Revisited: A Statistical Approach to Linguistics
Obviously these are made up, but I do think they serve the purpose. What's the part in bold called? Scientific articles often have this headline which is then followed by an explanatory subtitle, but I'm wondering whether this kind of headline has a specific term to describe it.
