✕Common Mistakes
Tu as le lait bio ?
Using the definite article ‘le’ changes the meaning to ‘the organic milk’ (a specific known milk) instead of ‘some organic milk’. For an indefinite amount you need the partitive ‘du’.
Tu as du lait bio ? (pronounced without liaison)
Learners sometimes forget the liaison and pronounce it as ‘as du’ with a hard ‘s’. In spoken French the ‘s’ links to the following vowel: [a dy].
Tu as du bio lait ?
Placing ‘bio’ before the noun (e.g., ‘bio lait’) is ungrammatical in French; the adjective must follow the noun.

Cultural Tip
In France, ‘bio’ products are regulated by the EU organic label and are very popular in supermarkets and farmers’ markets. The adjective ‘bio’ follows the noun (lait bio) unlike English where it precedes. When you ask for organic items, you can also say ‘produits bio’ or ‘aliments bio’. Remember that the informal ‘tu’ is only appropriate if you have a familiar relationship with the person you’re speaking to.
