Learn French: Ces tomates sont pour toi. - These tomatoes are for you.

Ces is the plural word for "these" or "those". Because tomates is plural, you must use ces. Unlike the singular forms (ce, cet, cette), ces is used for all plural nouns, whether they are masculine or feminine.

Does ces mean "these" or "those"?

It can mean either! In French, ces is used for both. If you ever need to specifically point out that the tomatoes are far away ("those over there"), you can add -là to the end of the noun: ces tomates-là.

Why does the sentence use toi instead of tu for "you"?

In French, you must use a stressed pronoun (like toi, moi, or lui) after a preposition like pour (for). Tu is a subject pronoun, so it is only used when "you" are the one doing the action, like in tu es (you are).

Which verb does sont come from?

Sont is the "they" form of the verb être (to be). Since "these tomatoes" is a plural subject (which acts just like "they"), we use sont to mean "are".
