The following sentence has been divided into four parts. Identify the part that contains an error.

Sentence:

This is / a doll / and there is / a umbrella

Error:

The error is in “a umbrella”

Correct rule:

We use:

• “a” before consonant sounds
• “an” before vowel sounds (a, e, i, o, u sound)

“Umbrella” starts with the vowel sound u, so we use “an”, not “a”.

Correct sentence:

This is a doll and there is an umbrella.

Final Answer:

Error is in: a umbrella

Extra facts:

• “An” is used before vowel sounds, not just vowel letters (e.g., an hour, a university).
• “University” starts with a “yu” sound, so we use a university, not “an university”.
