1. Verb:
   • To emerge or issue forth from a confined or narrow space into a broader, open area. This is the core meaning, often used for geographical features like rivers or streams flowing out of a constricted channel, or for military troops moving from a confined area like a defile, forest, or valley into open terrain.
