Running into debt is a common phenomenon for many individuals, businesses, and even governments. When people incur more expenses than their income or revenue can cover, they end up borrowing money to meet their financial obligations. Some synonyms for the phrase "run into debt" include "accumulating debt," "getting into debt," "falling into debt," "going into debt," and "building debt." These phrases all describe the same situation where an entity has borrowed money that it cannot immediately repay, leading to a debt burden. While borrowing money can be a useful tool for achieving financial stability or growth, it is crucial to manage debts responsibly to avoid accumulating excessive debts over time.
