Today’s Proverb (今日のことわざ)

“Penny wise, pound foolish.”


Origin or Interpretation(起源ないし解釈)

This proverb warns against the tendency to focus too much on saving small amounts of money while neglecting larger, more significant expenses. It suggests that being overly frugal with minor expenditures can lead to greater financial losses in the long run. The origin of this expression lies in the traditional British monetary system, where a penny was worth significantly less than a pound. Thus, the proverb underscores the importance of considering the bigger picture and making wise financial decisions that prioritize long-term benefits over short-term savings.

Example 3(例示3)
