✦Grammar Breakdown
Oui,j'aiungrandfrère.
Oui
Simple affirmation meaning “yes”. It can stand alone or start a sentence.
j' + ai (elision)
The subject pronoun “je” drops the e before a vowel‑starting verb, becoming “j’”.
un (indefinite article)
Used before a singular masculine noun to mean “a” or “an”.
grand + noun (age meaning)
When placed before a family member, “grand” indicates the older sibling, not size.
frère (masculine noun)
Means “brother”. The adjective must agree in gender and number (grand → grand).

✕Common Mistakes
Oui, j'ai un frère grand.
Placing the adjective after the noun (frère grand) changes the meaning and sounds unnatural.
Oui, je ai un grand frère.
The pronoun “je” must elide before a vowel‑starting verb: use “j’ai”.
Oui, j'ai un grand frère très grand.
In this context “grand” refers to age, not size; saying “un frère très grand” would be the correct way to talk about a tall brother.

Cultural Tip
In French families, “grand frère” is the everyday way to refer to the older brother, while “petit frère” means younger brother. The adjective “grand” before a sibling always signals age, not physical size. In formal writing you might hear “frère aîné”, but in spoken French “grand frère” is far more common.
