Ne ... aucun(e) = None (negation)

Look at these negative sentences:

Tu as une soeur? Aucune!Do you have a sister? None!

Il n'aime aucun programme de télé-réalité.He likes no TV-reality show.

The construction ne… aucun/aucune + [thing] means none or not one, or no [thing]

Note that aucun must agree in gender with the thing it refers to

BUT 

aucun/aucune never agree in number (singular/plural): as they describe an absence of things, they're always singular
