An Hour vs. A Hour: Make Sure You Get It Right!
Quick Tips:
The correct phrase is “an hour,” not “a hour.”
- Use “an” before words that start with a vowel sound (like “hour”).
- Use “a” before words that start with a consonant sound (like “house”).
An Hour vs. A Hour: Definition, Usage
An Hour:
- Meaning: Refers to a period of 60 minutes.
- Use: “An” is used instead of “a” before words that start with a vowel sound. In “hour,” the “h” is silent, so the word begins with a vowel sound (“our”).
- Example: “I’ll be there in an hour.”
- Explanation: “An” is the correct indefinite article here because the “h” in “hour” is not pronounced, and the word starts with a vowel sound.
A Hour:
- Incorrect: “A hour” is not correct because “a” is used before words that begin with a consonant sound. Since “hour” starts with a silent “h” and has a vowel sound (“our”), “an” should be used instead.
- Example of Incorrect Use: “I’ll call you back in a hour.”
Tips to Remember the Differences
- Identify the first sound of the word: if it begins with a vowel sound, use ‘an’; if it starts with a consonant sound, use ‘a’
- Always consider the sound and not the written form of the word
- Remember that ‘hour’ has a silent ‘h,’ making it an exception to the standard rule
