Question: What does the word “moat” mean?
Answer:
Moat — Definition & Meanings
1. Literal / Physical Meaning
A moat is a deep, broad ditch dug around a castle, fortification, building, or town, historically to provide it with a preliminary line of defence. Moats can be dry or filled with water.
A moat is one of the lines of defense for a castle — this water-filled ditch essentially means “Keep out!”
Other physical uses:
- A deep wide hole dug around an area in a zoo, used to stop animals from escaping.
Etymology: The word comes from the French mote/motte, meaning “mound.”
2. Figurative / Business Meaning (Economic Moat)
In modern usage, especially in business and investing, “moat” is used metaphorically:
A “moat” refers to a competitive advantage that protects a company from rivals — for example, a company’s moat was reduced when the patent on its devices expired.
This economic principle was coined by Warren Buffett in 1999, who advised investing in businesses “that have wide, sustainable moats around them.” The idea is: no matter how good your company’s product is, if there is no moat, competitors will invade your castle and burn it down.
Examples of business moats include:
- Brand loyalty
- Patents and intellectual property
- Network effects
- Proprietary data
- Cost advantages
