The phrasal verb "hinge on" is predominantly used in informal speech but can be encountered in formal contexts as well, particularly in written or academic settings. It means that something is very dependent or contingent upon something else for its success or outcome. The phrase often describes situations, decisions, results, or plans that rely heavily on a specific factor or condition. For example, one might say "The success of the project hinges on securing funding." It's frequently used in discussions about strategic planning, predictions, and cause-effect relationships, indicating a high degree of reliance or conditional dependence. Its usage conveys the idea of a pivotal point or crucial element upon which other aspects are dependent.
