All About Me
What do I look like?
To describe yourself you use ADJECTIVES. When they describe a NOUN, adjectives agree with its GENDER (whether it is masculine or feminine).
So when you’re talking about yourself, if you’re a girl, you use a feminine adjective, and if you’re a boy, a masculine one.
Je suis grand. - I am tall. (If you are a boy)
Je suis grande. - I am tall. (If you are a girl)
Je suis petit. - I am short. (If you are a boy)
Je suis petite. - I am short. (If you are a girl)
Colours are ADJECTIVES too. As well as GENDER, they agree with NUMBER (ie whether the NOUN is singular or plural).
So, 'blue' is bleu, but becomes bleue with a feminine noun eg la bouche bleue (the blue mouth), bleus with a masculine plural eg les yeux bleus (the blue eyes), and bleues with a feminine plural eg les bouches bleues (the blue mouths). The same is true of other colours.
