Question

he will return in a/an hour​

Answer 1

Answer:

he wil return in an hour

Answer 2

He will return in an hour.

• Here, "an" is the appropriate article to be filled in the given sentence.
• Articles are words used to indicate a noun without describing it.
• There are three articles a, an, and the in English grammar.
• The article "an" is used in front of vowels.
• Here when we spell the word "hour", "h" becomes silent making it a vowel word.
• Therefore an is the correct answer.
