Mistake, Error, and Fault

The words "mistake," "error," and "fault" are often confused or misused. While they can be interchangeable in certain contexts, they have distinct meanings and uses. Let's explore the differences between them with additional examples.

Mistake (noun or verb)

The word "mistake" can have different meanings depending on the context:

1. An unintentional wrong action, usually accidental or through inadvertence:

   • A mistake can also be due to occasional lapses or something done too hastily.

   • Examples:

     • "I made a mistake in his phone number. I wrote 243 instead of 245."

     • "There’s a mistake in the address. It’s Beach Road, not Beacon Road."

     • "I made a mistake when I took exit number 13. I read the directions too quickly."

     • "Make sure you check the text for spelling mistakes before you submit it."

     • "She made a mistake by not double-checking the meeting time."

2. Misguided judgment:

   • Examples:

     • "It was a mistake to send the boy to boarding school; he was very unhappy."

     • "Coming here was a mistake; it was a waste of time."

     • "She made the mistake of not taking her doctor's advice."

     • "Their decision to sell the house was a huge mistake."

     • "Investing in that company was a financial mistake."

3. Failure to differentiate:

     • "I mistook your umbrella for mine. I took yours by mistake!"

     • "Don't mistake the two buildings. The entrances are very similar."

     • "I mistook the salt for the sugar!"

Error (noun only)

The word "error" can also have different meanings:

1. Something wrong due to lack of knowledge or inaccurate information:

   • Examples:

     • "It was an error to include ‘good’ in the list of adverbs. ‘Good’ is an adjective."

     • "The brochure contains errors concerning the history of the region."

     • "‘She has visited the museum yesterday’ is a grammatical error."

     • "The air crash was due to human error."

     • "The scientist admitted to an error in the experiment's calculations."

2. In computing, there can be errors:

   • We write an error message but not a mistake message.

   • Examples:

     • "We lost a week’s work due to a computer error."

     • "Due to a computer error, the meeting was wrongly scheduled."

     • "Unfortunately, the computer error was detected too late."

     • "The actor's poor image is partly the fault of the press."

     • "The accident was entirely his fault for not paying attention."

2. Weakness or imperfection in a person’s character:

     • "In my opinion, Emily’s worst fault is impatience."

     • "He loves her in spite of all her faults."

     • "Nobody is perfect. We all have our faults."

     • "Her biggest fault is her tendency to procrastinate."

3. A defect in a machine, system, or design (causing damage or malfunction):

   • Examples:

Note: A blunder is a foolish or embarrassing mistake, especially one resulting from carelessness or lack of thought (a botch, a foul-up, a faux-pas). For example, "The politician made a blunder by making a premature announcement."
