Understanding the words "semaine" and "mois" in French is important if you want to learn basic vocabulary about days and months.

First, let's look at "semaine." This word means "week" in French. A week has seven days:

• lundi (Monday)
• mardi (Tuesday)
• mercredi (Wednesday)
• jeudi (Thursday)
• vendredi (Friday)
• samedi (Saturday)
• dimanche (Sunday)

You can practice using these days in sentences. For example:

• Je travaille lundi. (I work on Monday.)
• Nous avons une réunion vendredi. (We have a meeting on Friday.)

Now, let's move on to "mois." This word means "month" in English. A year has twelve months. Here they are:

• janvier (January)
• février (February)
• mars (March)
• avril (April)
• mai (May)
• juin (June)
• juillet (July)
• août (August)
• septembre (September)
• octobre (October)
• novembre (November)
• décembre (December)

It can help to use these months in sentences. For example:

• Mon anniversaire est en mai. (My birthday is in May.)
• Les vacances d'été commencent en juillet. (Summer holidays start in July.)

In summary, "semaine" means a seven-day period, and "mois" refers to a longer time, usually thirty or thirty-one days.

When you use these words, it's good to pair them with numbers. You can say:

• deux semaines (two weeks)
• trois mois (three months)

For example:

• Je vais partir pour trois mois. (I will leave for three months.)
• Il reste deux semaines avant les vacances. (There are two weeks left before the holidays.)

A key part of learning these words is practicing how to use them with numbers. You can make simple sentences like:

• Il y a quatre semaines dans un mois. (There are four weeks in a month.)
• Septembre a quatre semaines et trois jours. (September has four weeks and three days.)

Remember, learning new words is easier when you relate them to how we measure time in our daily lives. As you get more comfortable with "semaine" and "mois," try to learn other related words and phrases. Mixing new vocabulary will help you understand better and speak confidently!
