Rule of thumb
Rule of thumb means a broadly accurate guide based on practice. It is a general principle that provides a practical solution or guideline for making decisions or judgments.

Explanation:
- This phrase originates from the use of the thumb as a rough measurement.
- It is not an exact or scientific measurement but is typically a practical and convenient method for quick estimation.

Example:
- A common rule of thumb for tipping at a restaurant is to leave around 15-20% of the bill as a tip.
- Another rule of thumb in investing is to diversify your portfolio to reduce risk.

Usage in a sentence:
- "As a general rule of thumb, it's a good idea to start saving for retirement early."
