The phrase "hand to mouth" is often used to describe a financial situation where someone lives paycheck to paycheck, barely managing to make ends meet. However, there are several other ways to express this same sentiment. For example, one could use phrases like "just scraping by," "living from one paycheck to the next," or "barely keeping their head above water." Other synonyms for "hand to mouth" might include "penny-pinching," "financially tight," or "economically challenged." Whatever phrase you choose to use, the underlying meaning remains the same - struggling to get by on limited resources.
