Expert writing Tips
Best practice
Always use "an hour or two" instead of "a hour or two" to ensure correct grammar. The article "an" is used before words that begin with a vowel sound.
Common error
Avoid using the indefinite article "a" before the word "hour". The correct article to use is "an" because "hour" begins with a vowel sound, even though the letter 'h' is a consonant. For example, it's correct to say "I'll be there in "an hour"" not "I'll be there in a hour".

Ludwig's WRAP-UP
The phrase "a hour or two" is grammatically incorrect. As Ludwig AI indicates, the correct usage is "an hour or two" due to the vowel sound at the beginning of the word "hour". Although the intent is generally understood, using the correct grammar enhances clarity and credibility. The phrase functions as an adverbial of time to estimate a short duration. While examples exist across various sources, including News & Media and Wiki, the low frequency and grammatical error suggest using alternative phrases like "a couple of hours" or "one or two hours" for improved correctness and formality.
