Learn French: J'ajoute du beurre à la recette. - I am adding some butter to the recipe.

In French, you cannot just leave a noun by itself. When talking about an unknown or uncountable quantity of something (like food or liquids), you must use a partitive article. Since beurre is masculine, we use du. It translates to "some butter" in English, even though we often just drop the "some" in everyday English.

How do I know if I should use "du", "de la", or "de l'" for food?

It always matches the gender and starting letter of the noun! Use du for masculine words (like du beurre), de la for feminine words (like de la soupe), and de l' for any word starting with a vowel or silent h (like de l'eau).

Why is "J'ajoute" written with an apostrophe instead of "Je ajoute"?

When the word je (I) comes right before a verb that starts with a vowel, the e is dropped and replaced with an apostrophe. This is called elision, and it makes pronunciation smoother. Since ajoute starts with an a, it must become J'ajoute.

Does "à la" just mean "to the" here?

Yes! The verb ajouter (to add) is usually followed by the preposition à (to). Because recette (recipe) is a feminine word, we use the feminine article la (the). Put them together, and à la recette exactly means "to the recipe".
