hi !
1- Are you going to the swimming pool ?
2- Are you going to school ?
3- Is your father going to the post-office today ?
4- What's on the table ?
5- Le pull est vert , plural form =Les pulls sont verts le = les- pull, you add ans s/ verb être 3rd person plural = sont/ vert= colour adjective taking an S
The colour adjectives as blanc, noir, rouge, vert, bleu,....... designing only colours agree in gender and number with the noun they qualify.
Des jupes rouges et bleues. Des pantalons noirs Une robe blanche
Except colours which are nouns as chocolat , orange, marron,turquoise, or, cerise, crème......
except "rose, mauve, fauve" . All the others that maybe noun will never agree.
the you have compound colors.....it's a bit more difficult
hope it helps !
